R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Since the rollers can simply roll, the chain is appropriate for running to the floor though the rollers obtain the dwell load.
F-roller Conveyor Chains have rollers with the exact same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting to the lateral sides on the chain, the chain is suitable for getting each a dwell load plus a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized than the width of plates.
An M roller is intended for smoother engagement together with 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 than that in the M-roller.
The chain is suitable for vertical conveyance in which rollers are significantly less likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mainly identical construction to R-roller and F Conveyor Chains, respectively, except for that bearings within for smoother rotation.
6.UR- and UF- Rollers (huge clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical construction to R-roller and F Conveyor Chains, respectively. On the other hand, the clearances among the outer diameter of bushings and the inner diameter from the rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
