R-roller Conveyor Chains have rollers with an outer diameter greater than the width of plates.
Because the rollers can simply roll, the chain is appropriate for working over the floor even though the rollers get the live load.
F-roller Conveyor Chains have rollers with all the similar outer diameter as that of R-roller but with flanges.
Since the flanges can get the force acting on the lateral sides in the chain, the chain is suitable for getting the two a reside 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 made for smoother engagement with the sprockets. Since the chain is light in weight, it’s appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of the M-roller.
The chain is suitable for vertical conveyance in which rollers are much less more 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 for your bearings inside for smoother rotation.
6.UR- and UF- Rollers (massive clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively. Having said that, the clearances amongst the outer diameter of bushings as well as the inner diameter on the rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
