R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can conveniently roll, the chain is suitable for running on the floor whilst the rollers get the dwell load.
F-roller Conveyor Chains have rollers with all the very same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting on the lateral sides from the chain, the chain is suitable for obtaining the two a dwell load as well as a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller than the width of plates.
An M roller is designed for smoother engagement using the sprockets. Since the chain is light in fat, it’s ideal for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that in the M-roller.
The chain is appropriate for vertical conveyance where rollers are much less likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical construction to R-roller and F Conveyor Chains, respectively, except for that bearings inside for smoother rotation.
6.UR- and UF- Rollers (huge clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have primarily identical structure to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances amongst the outer diameter of bushings as well as the inner diameter with the rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
