Conveyor Chain - Tsubaki

Side Roller Free FlowChainSectionBDOUBLE PITCH TYPERS TYPERS POLY-STEEL TYPEOutboard Roller Chain with Side Rollers (Side Roller Chain) is used for free flow conveyance. Usually two strands are used on theequipment. Side Roller Chain is based on standard roller chain with side rollers installed on extended pins. There are three types ofbase chain:(1) Double pitch roller chain with standard rollers (straight side plates, small rollers).(2) Double pitch roller chain with oversize rollers (straight side plates, oversized rollers).(3) RS-type (figure-eight side plates, small rollers; oversized rollers are not available).The construction of our Side Roller Chain makes for a highly compact conveyor system. This is further enhanced by the chain'scapacity to flex backward, requiring minimum space on the return side of the operation. Since a large number of rollers can beinstalled, a conveyor can easily be made where small objects are placed directly on the chain. Quick starting is also possible byinstalling high friction brake rollers.You can select various combinations of base chain materials and side rollers. Available base chains are: carbon steel, lube-freeLambda or poly-steel. Plastic or steel side rollers may be attached to the base chain. Small sprockets can be used with the RS-typeto minimize conveyor height. Because the side roller diameter is larger than the chain pitch for the RS-type, side rollers cannot beinstalled on every pitch on the same side of the chain. Side rollers can be installed in alternating positions - staggered or horrizontal.Staggered rollers tend to allow pallets to run smoother. In double pitch type, the diameter and width of the side roller are different forStandard and Oversize rollers. When the stopper in a free flow conveyor is released, pallets accelerate to the chain speed. Thisacceleration is determined by the coefficient of friction between the side roller and the pin. The smaller the coefficient of friction, thelonger it takes for the pallets to reach the speed of the chain. Faster acceleration can be accomplished by installing brake rollers. Inplastic side roller products from Tsubaki, the coefficients of friction of chain are: with brake, 0.10; without brake, about 0.06.Side Roller Chain has the following characteristics compared to Double Plus Chain:1. Greater allowable load (using carbon steel base chain for each).2. More economical. C2050 Side Roller Chain costs about half as much, and sprockets cost about two-thirds that of the equivalent size ofDouble Plus Chain.3. More noise. Comparing systems with the same pallet speed and sprockets with the same number of teeth, Side Roller Chain emits about10 to 15 dB more noise than Double Plus Chain.4. Because the body of Side Roller Chain is exposed over the guide rail, this chain does not have the same safety features as Double Plus.5. Snap covers are not available for Side Roller Chain; and so it is difficult to prevent small objects from falling in between chaincomponents.6. Complete kits for Side Roller Chain, including the guide rails and other components, are not available. Therefore, you have to createyour own system.Standard sprockets may be used. In some cases, side rollers may interfere with the sprocket hub. Additional machining of the hubmight be required.Conveyor Chain B90Tsubaki of Canada Limited, 1630 Drew Road, Mississauga, ON L5S 1J6 Tel: 905-676-0400 Fax: 905-676-0904 Toll-Free: 800-263-7088 www.tsubaki.ca e-mail: info@tsubaki.ca
