R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Because the rollers can easily roll, the chain is suitable for running over the floor when the rollers acquire the live load.
F-roller Conveyor Chains have rollers with all the exact same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting about the lateral sides of the chain, the chain is suitable for receiving the two a dwell load along with a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller than the width of plates.
An M roller is made for smoother engagement with all the sprockets. Because the chain is light in weight, it is appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of the M-roller.
The chain is ideal for vertical conveyance exactly where rollers are much less likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
6.UR- and UF- Rollers (big clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical structure to R-roller and F Conveyor Chains, respectively. Having said that, the clearances between the outer diameter of bushings along with the inner diameter of the rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
