one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter greater than the width of plates.
Because the rollers can very easily roll, the chain is suitable for operating to the floor although the rollers obtain the live load.
two.F-roller
F-roller Conveyor Chains have rollers using the similar outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting on the lateral sides in the chain, the chain is suitable for receiving the two a reside load as well as a lateral load.
3.M-roller
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 together with the sprockets. Since the chain is light in fat, it’s suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of your M-roller.
The chain is suitable for vertical conveyance exactly where rollers are less more likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have largely identical framework to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
six.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. On the other hand, the clearances among the outer diameter of bushings as well as the inner diameter in the rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
