R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can effortlessly roll, the chain is suitable for operating to the floor though the rollers obtain the live load.
F-roller Conveyor Chains have rollers together with the very same outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting over the lateral sides from the chain, the chain is appropriate for obtaining each a dwell load and a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller compared to the width of plates.
An M roller is intended for smoother engagement together with the sprockets. Because the chain is light in fat, it can be suitable for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of the M-roller.
The chain is appropriate for vertical conveyance wherever rollers are significantly less prone to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mostly identical construction to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
6.UR- and UF- Rollers (big clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical framework to R-roller and F Conveyor Chains, respectively. On the other hand, the clearances in between the outer diameter of bushings as well as the inner diameter on the rollers are enlarged to prevent the rollers from repairing when foreign matters enter.
