R-roller Conveyor Chains have rollers with an outer diameter greater compared to the width of plates.
Because the rollers can simply roll, the chain is ideal for working on the floor while the rollers receive 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 receive the force acting on the lateral sides in the chain, the chain is suitable for receiving each a live load in addition to 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 created for smoother engagement with all the sprockets. Since the chain is light in bodyweight, it’s appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is suitable for vertical conveyance where rollers are much 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 to the bearings inside for smoother rotation.
six.UR- and UF- Rollers (large clearance in 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 between the outer diameter of bushings and the inner diameter on the rollers are enlarged to stop the rollers from fixing when foreign matters enter.
