MANUAL 

Chain description starts with the material, followed by an S for straight running, M for Magnetex, B for bevel or T for tab side-exing chains, 

followed by the width and nally the execution: S for Slideline, X for X-line, M for Max-Line and R for Rubber. For example 60 S 31 XM is a 60-Series 

straight running 3 ¼” wide chain with Max-Line and X-Line. 

X-line Chains have extreme precision atness and superior sliding properties 

Slideline Chains offer very close tolerances with respect to atness and surface nish. 

Max-line Chains take care of perfect product support, thanks to maximum plate surface.

New 1270 series sprocket now with a double row of teeth, works bi-directionally and engages all areas 

of the 1270 belt thus providing a far superior drive action with no "slippage" compared to outdated 

single tooth sprockets that only engage on a single area of the belt. This double row of teeth also 

eliminates any misalignment and makes installation far easier and simpler.

The sand/slurry testing method rotates a sample in quarts slurry for 24 hrs @ 1200 rpm and measures the volumetric loss. However, this is not necessarily a reflection of 

wear under low stress sliding abrasion conditions. The lower this figure, the better.

Whille every care has been taken in the compilation of this data based on the tests from authorative sources and practical experience, no liability can be accepted. 

UHMWPE WEAR STRIPS 

Wear strips are used to reduce wear or erosion in mechanical systems. They are used wherever abrasion, impact, or heat may cause wear and tear 

on mechanical components. The proper selection of wear strips, plates and parts requires an understanding of both application requirements and 

product specications. Wear Strips protect manufacturing machinery from abrasion or impact. UHMWPE wear strips are resistant to the abrasive 

effects of the bulk processing of grain, ore, salt, limestone, coal, glass, and y ash. Anti-static and UV treated grades are available on request. 

• Used as a sliding support for plastic modular belts and chains, or as a guiding aid for various purposes; 

• Used in a wide range of industries such as bottling, packaging, materials handling, and food processing. 

ADVANTAGES 

• Lower drag and noise 

• Shock absorbing & self-lubricating 

• Very low coefcient of friction 

• High impact and bending strength 

• FDA approved 

• No moisture absorption 

• Bacteria free & hygienic 

• Reduced power requirements 

• Excellent chemical resistance, erosion 

and abrasion resistant 

• Environmentally friendly and recyclable 

UHMWPE CHAIN GUIDES 

Conveying Components & Industrial Chain Guides for Roller Chains: Industrial chain guides are available in UHMWPE, which meets guidelines for food 

handling, including those from FDA, USDA and 3-A Dairy. UHMWPE self-lubricating surface minimizes friction and extends chain life. UHMWPE 

industrial chain guides are quiet, reduces noise and are made for use with plastic or metal chains. 

APPLICATIONS 

Wear strips, sliding supports and guides, as well as curved and straight tracks that are extruded or machined, are used in many industries, including 

bottling, packaging, mechanical, pharmaceutics, ceramics, glass, food processing, paper, etc. UHMWPE offers impact resistance, tensile strength at 

high temperatures, and energy absorption under high stress levels.

124 Wear Strips

CHAIN GUIDES 













CHAIN GUIDES 

IRP's Ultra High Molecular Weight Polyethylene Wear Strips, Chain Guides, Curves and Tracks deliver properties of wear resistance, self 

lubrication, water resistance, acid resistance, anti-vibration/noise dampening, dirt repellent and are light weight which makes it an ideal 

material for support and guiding of standard chain sections. Use of these sections not only support the chain but also prevent chain 

vibration and assists in reducing effect of drag which extends the expectancy of chains and belts. 

Conventional guide rails manufactured from sheet or other metal are frequently responsible for excessive wear of rollers and links, 

particularly if lubrication is not provided. 

The increasing requirements of noise, hygiene, health and safety make the use IRP's Ultra High Molecular Weight Polyethylene and nylons 

particularly useful in the design of machinery incorporating chains and belts.

pg. 4 

Slip Stick / Pulsating Effects 

Slip-stick is caused by the difference between static friction and dynamic friction. Slip-stick 

effects can cause a pulsating chain operation. 

SLATBAND 

pg. 166 

The chance of a pulsating operation increases with long, low speed conveying. 

 

Level in/outfeed 

Inclining / Declining Conveyor Configuation 

Slatband chains can be used on in- or declined conveyors which are basically constructed in 

the same way as level conveyors. Main concern is to avoid that the products slide down or tip. 

Conveyors can be constructed with a level in/outfeed section, see diagrams on the left. 

MATERIAL 

pg. 3 

Inclined/declined conveyors that are equipped with a Magnetic Flex curve, we recommend a 

minimum level section of 1mtr. This eliminates the chance of the chain lifting out of the curve. 

Max. Possible Angle 

The maximum possible angle depends on several factors: Coefficient of friction between chain 

and product; acceleration/deceleration; product stability and external factors like dirt or debris. 

Below is a general table showing maximum angles determined by chain friction.

Straight Running Configuration 

The length of a conveyor is not limited. There is a certain maximum length for each application. The 

limits are depending on factors like chain - or belt type, lubrication, kind of product, load. The exact 

maximum conveyor length can be calculated with the readily available calculation programme. 

SLATBAND 

pg. 166 

Generally for straight running conveyor we recommend a Max. track length of 12 mts. (see 

diagram) 

Shorter conveyors are built to obtain lower backline pressure by means of better control facilities. 

The chainspeeds can be controlled using frequency controlled drives. When for instance one 

conveyor runs full, the chainspeed of the preceding conveyor can then slowly be decreased. 

Pasteurisers, warmers and coolers can require longer tracklengths.

• Minimise the number of corners whenever possible. 

• When conveying from point A to point B, design the conveyors so that the drive is positioned 

further from the last corner (see diagram), resulting in lower chain tension and maximising

Tensioner Construction

140° 


A tensioner construction is only necessary if the conveyor design does not allow for a proper 

catenary sag. A tensioner can also be used with declined conveyors, but in all other cases it is 

not recommend to tension the chain/belt. 

The tensioner roller/sprocket can be fixed on an arm or move up and down in slots in the 

conveyor sideplates. This will bring constant tension, independent of length differences in the 

chain.

roller. At the same time it is recommended not to exceed the maximum diameter, because the roller 

friction may be too high to be set in motion by the belt.

Metal Wearstrips 

WEARSTRIP MATERIALS 

Metal wearstrips can be used in most situations using plastic chains and are strongly recommended in abrasive environments. 

pg. 4 

SLATBAND 

Stainless steel: 

• Recommended for abrasive conditions due to avoiding of dirt embedding in the wearstrips; 

• Recommended for plastic chains/belts in dry environments with speeds > 60m/min; 

• Cold rolled stainless steel with a hardness of at least 25 Rc and a surface finish of maximum 1.6 μm is recommended; 

• Best results can be achieved by using stainless steel AISI 431 

• AISI 304 is not recommended as wearstrip material. 

pg. 114 

WEARSTRIPS 

pg. 166 

Plastic Wearstrips 

Friction is low compared to steel wearstrips. Two types of plastic are suitable to be used as a wearstrip material. 

UHMWPE: 

• Most common used wearstrip material with extreme low friction; 

• Excellent resistance against many chemicals; 

• Virtually no moisture absorption, therefore very suitable for lubricated lines; 

• Good dimension stability; 

• Reduces some of the noise conveyors produce; 

• Suitable for dry running conveyors with speeds up to 60 m/min; 

• Extruded quality 1000 grade UHMWPE is recommended. 

MATERIAL 

pg. 3 

GENERAL 

INDEX 

Polyamide/Nylon: 

• Relatively high moisture absorption which makes the material expand; 

• Polyamide is also used with additives to reduce the coefficient of friction; 

• Suitable for dry running high speed conveyors.

UHMWPE WEARSTRIP INSTALLATION 

Chamfering of Wearstrips 

Wearstrips should always be chamfered at the beginning of the strip where they are fixed. 

Chamfering reduces the risk of chain-obstruction resulting in a smooth operation.The wearstrips 

should be chamfered at the sides and at the top. 

pg. 4 

SLATBAND 

pg. 114 

WEARSTRIPS 

pg. 166 

MATERIAL 

Gap 

Splitting the Wearstrips 

On straight sections with a length of more than 3 metres, or for high (40° - 70°C) application 

temperatures, we recommend to divide the wearstrip into several sections, because of the thermal 

expansion of the strips. 

It is recommended to cut the wearstrips at 45° angles to provide smooth chain/ belt transfers. Make 

sure only the infeed side of the wearstrip is fixed to the conveyor frame to avoid bulging of Gap the 

wearstrips. 

pg. 3 

GENERAL 

INDEX 

Calculation Example 

For UHMWPE material the expansion coefficient is 0.2 mm/m/°C. A temperature increase of 20°C 

would elongate a 3 meter wearstrip with: 

20°C * 3mtr * 0.2=12 mm 

In this case, the gap between the wearstrips should be a bit larger than 12 mm. 

We recommend a maximum wearstrip length of 6mtr. with UHWMPE wearstrips. 















POSITION SPROCKET - WEARSTRIPS 

L 

When the chain enters the sprocket, it tends to raise and fall slightly (chordal action). For this 

reason the sprockets should be mounted in such a way that its highest point is no higher than the 

top of the wearstrips. The front edges of the wearstrips should be bevelled to allow smooth and 

free running of the chain. The distance from the end of the wearstrip to the sprocket shaft centerline 

should equal dimension L, otherwise the wearstrip will interfere with the free articulation of the 

chain as it enters the sprockets.

Installing Magnetic Flex Curves 

Magnetic Flex curves are mounted to the conveyor frame using inserts in the curve returnpart. The 

upperpart is fixed to the returnpart with screws. 

It is important to take care of the position of the inserts. Magnetic Flex curves should only be drilled 

in the underpart, taking the dimensions into account shown in the drawing.

• Check running direction, since the chain should always be driven at the fixed hinge eyes. 

Running direction is shown at the underside of the chain. 

• Do not tension the chain when installing. Tensioning will result in a higher chainlaod and more 

wear of components. During installation the proper tension is manually achieved. 

CHAIN INSPECTION & MAINTENANCE 

• A good condition of the line can be maintained when people recognise signs of initial and react accordingly. Following aspects are of importance 

during regular check-up. 

• Check the condition of the chain regularly, and replace links which are damaged. Important in this matter is to try to find the cause of the damaged 

links. Wear patterns or damage on a chain can often lead you to a problem area elsewhere in the conveyor. 

• Check the amount of catenary sag and remove links or modules when the catenary chains exceeds prescriptions. Remember catenary grows 

during full load. 

• Check if the returnrollers turn freely, repair or replace if not. 

• In case of lubrication check if the lubrication system operates properly. 

• Check carryways and wear strips for excessive wear or peculiar wear patterns. 

• Check positions of transfer plates and check the fingerplates for broken/ worn parts and repair or replace if necessary.

Time to Replace 


Chain Replacement 

We recommend to replace slatband chains, if the following is the case: (see diagrams) 

• Chain is elongated more then 3%, see below. 

• The thickness of the topplate of the slatband chain is reduced to 2.0 mm. 

• The surface becomes unflat or very rough due to (uneven) wear, especially in applications 

where product handling is critical. 

• Side of the hinge of sideflexing chains wears away and exposes the pin. 

• The Chain Jumps on the Sprocket. 

It is also important to look at the position of the chain in the productionline. Chains that run on a 

pressureless inliner, have to be replaced all at once. If only one chain is replaced there will be a 

chance of unacceptable height differences, which could result in products topping over.

Magnetic Flex Replacement 

Replacement is recommended: 

• If uneven wear patterns, and unacceptable wear of the track are found. The chain can easily be 

lifted out of the curve for inspection. 

• The chain reaches the inside of the curve, see picture. In multiple track curves, check if the wear 

rate is similar in all tracks. It is also important that the wear of the curve groove still shows a 

straight angle of 90o with the horizontal surface. 

Sprocket & Idler Replacement 

• The teeth show a hookshape, which obstructs the chain. 

• Replace sprockets when teeth are damaged or when chain jumps on the sprocket. 

• The idler is oscillating on the shaft, because of a worn bore. 

If chain is replaced due to elongation, always install new sprockets! 

Wearstrip Replacement 

• When chains are replaced always replace the wearstrips. 

• Dirt or debris is embedded in the wearstrip material in unacceptable amounts.

Level in/outfeed 

We have the experience that with long, low speed conveyors, the chance of a pulsating 

operation increases. 

Inclining / Declining Conveyor Configuation 

Modular Belts can be used on in- or declined conveyors which are basically constructed in the 

same way as level conveyors. Main concern is to avoid that the products slide down or tip. 

Conveyors can be constructed with a level in/outfeed section, see diagrams on the left. 

MATERIAL 

pg. 3 

No in/oufeed 

In case the inclined/declined conveyor is equipped with a Magnetic Flex curve, we 

recommend a minimum level section of 1mtr. This eliminates the chance the chain is lifted 

out of the curve. 

Max. Possible Angle 

The maximum possible angle is depending on several factors: Coefficient of friction between chain 

and product; acceleration/deceleration; product stability and external factors like dIrt or debris. 

Below a general table is shown with maximum angles determined by chain friction.

Metal wearstrips can be used in most situations using plastic belts and are strongly recommended in abrasive environments. 

pg. 60 

MODULAR 

BELTS 

Stainless Steel: 

• Recommended for abrasive conditions due to avoiding of dirt embedding in the wearstrips; 

• Recommended for plastic chains/belts in dry environments with speeds >60m/min; 

• Cold rolled stainless steel with a hardness of at least 25 Rc and a surface finish of maximum 1.6 μm is recommended; 

• Best results can be achieved by using stainless steel AISI 431. 

• AISI 304 is not recommended as wearstrip material. 

Plastic Wearstrips 

Friction is low compared to steel wearstrips. Two types of plastic are suitable to be used as a wearstrip material. 

UHMWPE: 

• Most common used wearstrip material with extreme low friction; 

• Excellent resistance against many chemicals; 

• Virtually no moisture absorption, therefore very suitable for lubricated lines; 


• Reduces some of the noise conveyors produce; 

• Suitable for dry running conveyors with speeds up to 60 m/min; 

• Extruded quality 1000 grade UHMWPE is recommended.

Chamfering of Wearstrips 

MODULAR 

BELTS 

Wearstrips should always be chamfered at the beginning of the strip where they are fixed. 

Chamfering reduces the risk of chain-obstruction resulting in a smooth operation.The wearstrips pg. 114 

should be chamfered at the sides and at the top.

MATERIAL 

Gap 

Splitting the Wearstrips 

On straight sections with a length of more than 3 metres, or for high (40° - 70°C) application 

temperatures, we recommend to divide the wearstrip into several sections, because of the thermal 

expansion of the strips. 

It is recommended to cut the wearstrips at 45° angles to provides smooth chain/ belt transfers. 

Make sure only the infeed side of the wearstrip is fixed to the conveyor frame to avoid bulging of the 

wearstrips. 

pg. 3 

GENERAL 

INDEX 

Calculation Example 

For MCC 1000 UHMWPE material the expansion coefficient is 0.2 mm/m/°C. A temperature 

increase of 20°C would elongate a 3 meter wearstrip with: 

20°C * 3mtr * 0.2=12 mm 

In this case, the gap between the wearstrips should be a bit larger than 12 mm. 

We recommend a maximum wearstrip length of 6mtr. with UHWMPE wearstrips.

When the chain enters the sprocket, it tends to raise and fall slightly (chordal action). For this 

reason the sprockets should be mounted in such a way that its highest point is no higher than the 

top of the wearstrips. The front edges of the wearstrips should be bevelled to allow smooth and 

free running of the chain. The distance from the end of the wearstrip to the sprocket shaft centerline

GENERAL 

INDEX 

Shafts 

In all situations stainless steel is recommended for shaft material. Metaloxydes that come from 

rusty shaft are extremely abrasive and would therefore reduce the wearlife of the conveyor 

components. It is also important to use shafts with a sufficient hardness and a smooth surface. The 

shaft diameter depends on the conveyor load and its width. 

Note: Maximum deflection of the shaft must not exceed 2 mm. Depending on the load and 

shaftlength, it can be necessary to use a larger diameter shaft or an extra bearing in the 

middle of the shaft to reduce the shaft deflection. 

Shaft Tolerances 

It is important that the tolerance of the shaft meets the specifications of the sprocket, so the 

sprocket can slide over the shaft at all times. In combination with all IRP sprockets the following 

shaft specifications are required, depending on the shaft diameter.

INSPECTION OF MODULAR BELTS 

A good condition of the line can be maintained when people recognise signs of initial wear/ failure are recognized and reacted to early. Following 

aspects are of importance during regular check-up. 

pg. 60 

MODULAR 

BELTS 

• Check the condition of the chain/ belt regularly, and replace links/ modules which are damaged. Important in this matter is to try to find the cause 

of the damaged links/ modules. Wear patterns or damage on a chain or belt can often lead you to a problem area elsewhere in the conveyor. 

• Check the amount of catenary sag and remove links or modules when the catenary of the chains exceeds prescriptions. Remember catenary 

could be larger under load. 

• Check if the returnrollers turn freely, repair or replace if not; 

• Remove dirt and debris which is stuck in the grid of the belt or inbetween the chain/ belt and the conveyor construction. 

• In case of lubrication check if the lubrication system operates properly. 

• Check carryways and wear strips for excessive wear or peculiar wear patterns. 

• Check positions of transfer plates and check the fingerplates for broken/ worn parts and repair or replace if necessary. 

Note: It is very important to replace damaged modules in plastic belts and links in plastic chains as soon as possible since small damage could 

lead to bigger damage if it is not repaired. If any damage is found such as pieces of plastic broken off, or a wear pattern at the side of the 

belt, the cause of the problem should be located.

CLEANING 

Cleaning Instructions 

To be able to keep production lines running at highest efficiency, cleaning is most important. Cleaning should include the removal of grease, dirt, 

dust and bacteria from the chain/ belt and components. Cleaning is important because it gives the following results: 

• Disinfecting results in a hygienic system 

• Products will be cleaner when they are packed 

• Reduction of friction between chains/belts and products results in less tipping products and less wear. 

• Removal of abrasive particles for longer wear life and components. 

Note: It is recommended always to flush the chain/ belts with plenty of water after having the chains/ belts cleaned, to remove the cleaning agent 

from the conveyor. 

Cleaning Dry Running Conveyors 

With dry running conveyors there is no continuous cleaning like with lubricated conveying. All products (beer or lemonade) spilled on the chain/ belt 

will result in pollution of the containers, increasing the friction, and the risk of products toppling over. 

Therefore dry running conveyors should be cleaned even more frequently than lubricated chain. How often depends on the circumstances, e.g. 

when sweet liquids are bottled and spilled, it might be necessary to clean every time the line stops for a few hours. 

Cleaning Plastic Belts 

Cleaning of plastic belts is not different from cleaning plastic chains. Again, the chemical resistance of the materials against the cleaning agents 

must be checked beforehand. 

Flat Top belts have to be cleaned from the top and underside. Flush Grid and Raised Rib belts can be cleaned very effectively, due to the open area. 

Water can be sprayed through the belt to clean it. 

When wide belts are cleaned at a high temperature (e.g. in a pasteurizer), there must be enough space for expansion

the sprockets should be mounted in such a way that their highest point is no higher than the top of 

the wearstrips. The front edges of the wearstrips should be bevelled to allow smooth and free 

running of the chain. The distance from the end of the wearstrip to the sprocket shaft centerline

Wearstrip Materials 

Stainless Steel Wearstrips 

Can be used in most situations using plastic 

belts and are strongly recommended in 

abrasive environments. 

Uhmpwe Wearstrips 

Friction is low compared to steel wearstrips. 

Two types of plastic are suitable to be used as 

a wearstrip material. 

• Recommended for abrasive conditions 

due to avoiding of dirt embedding in the 

wearstrips; 

• Recommended for plastic chains/belts in 

dry environments with speeds > 60m/min; 

• Cold rolled stainless steel with a hard-ness 

of at least 25 Rc and a surface finish of 

maximum 1.6 μm is recommended; 

• Best results can be achieved by using 

stainless steel AISI 431 (Werkstoff-Nr. 

1.4057 material; soft AISI 304 (Werkstoff- 

Nr. 1.4301) is not recommended as 

wearstrip material. 

• Most common used wearstrip material 

with extreme low friction; 

• Excellent resistance against many 

chemicals; 

• Virtually no moisture absorption, therefore 

very suitable for lubricated lines; 


• Reduces some of the noise conveyors 

produce; 

• Suitable for dry running conveyors with 

speeds up to 60 m/min; 

• Extruded quality 1000 grade UHMWPE is 

recommended.

Belt Return 

For sideflexing belts we recommend to use rotating rollers for the returnpart. Reduced wear. 

• Simple construction. 

• Good accessibility 

• Only point contact between chain/ belt and roller. – 

• small rollers may cause a rattling sound. 

Rollers should rotate freely therefore, rollers with rubber cover are recommended.

CURVE SYSTEMS 

A chain has to be kept in a curve to avoid the chain to jump up from the curve. There are 3 different 

curve systems commonly in use (See diagrams on your left) 

pg. 166 

MATERIAL 

Tab 

There can be different arguments when choosing a curve system: 

• Cost 

• Clean-ability 

• Easy Maintenance 

• Security 

• Possible presence of foreign particles 

• Abrasive Conditions 

• Inspector Demands 

• Side Transfers 

• etc.

Especially with unstable products and a multiple strand situation Bevel and 

Tab have a disadvantage: the link is lifting somewhat in the curve creating a 

“step” between the individual strands. 

With the Magnet System the links remain flat on the curve

Thermal Expansion Factors (f) are: 

Calculation: 

LF (Acetal) ~ 0.12mm/m/°C Expected Expansion mm = W * T * f 

NG (New Generation) ~ 0.13mm/m/°C W = Belt Width (mm) / 1000 

PP (Polypropylene) ~ 0.15mm/m/°C T = Temperature Difference ( °C-21°C) 

To be able to absorb the thermal expansion the belt needs some clearance on the side. Depending on the expected temperature difference the 

structure should be wide enough to make sure the belt will not get stuck at high temperatures or, in case of low temperatures, be small enough to still 

support the belt at low temperatures.
