Straight Running and Sideflexing Chains
Different returnpart constructions
There are several ways to guide a chain or a belt in the returnpart of a conveyor. The most common ways are by means of return rollers, wearstrips or
return guide shoes. Below a comparison is given for different systems.
Return Way “serpentine style”

+ Full support of the chain over the lenght of the conveyor.
+ Reduced noise in returnpart.
– More complex construction and less favourable accessibility for
maintenance.
– Less possibility to absorb chain elongation.
– Uneven wear of the chain when not supported over entire width
– Higher friction.
Material used for wearstrips should be UHMWPE

+ Reduced wear of the chain surface due to the reduction in speed
difference and the reduced friction.
+ Simple construction and good acessibility of returnpart.
+ Debris that falls upon the chain in the returnpart of the conveyor
is ejected by the movement of the chain.
– Only point contact between chain and roller.
Rollers must be able to rotate freely at all times. Small roller may
cause a rattling sound

+ Debris that falls upon the chain in the returnpart of the conveyor
is ejected by the movement of the chain.
+ Suitable for LBP chains.
– Risk of uneven wear of the chain surface when abrasive particles
are embedded in the plastic guideshoes.

– High friction.
Minimum guide shoe radius is 200 mm
