R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Because the rollers can effortlessly roll, the chain is suitable for working on the floor even though the rollers get the live load.
F-roller Conveyor Chains have rollers with all the same outer diameter as that of R-roller but with flanges.
Since the flanges can receive the force acting about the lateral sides of your chain, the chain is appropriate for acquiring both a dwell load along with a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller than the width of plates.
An M roller is created for smoother engagement using the sprockets. Because the chain is light in fat, it’s appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of your M-roller.
The chain is ideal for vertical conveyance in which rollers are much less likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have primarily identical framework to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
6.UR- and UF- Rollers (large clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have mostly identical framework to R-roller and F Conveyor Chains, respectively. However, the clearances between the outer diameter of bushings as well as the inner diameter of your rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
