1.R-roller
R-roller Conveyor Chains 
have rollers with an outer diameter larger than the width of plates.
Because the rollers can quickly roll, the chain is suitable for running on the floor when the rollers get the reside load.
two.F-roller
F-roller Conveyor Chains have rollers with all the identical outer diameter as that of R-roller but with flanges.
Because the flanges can get the force acting on the lateral sides on the chain, the chain is appropriate for acquiring each a dwell load plus a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller than the width of plates.
An M roller is intended for smoother engagement with all the sprockets. Because the chain is light in fat, it truly is ideal for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that with the M-roller.
The chain is appropriate for vertical conveyance in which rollers are significantly less likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical structure to R-roller and F Conveyor Chains, respectively, except for that bearings inside for smoother rotation.
six.UR- and UF- Rollers (significant clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical construction to R-roller and F Conveyor Chains, respectively. Having said that, the clearances concerning the outer diameter of bushings and also the inner diameter of your rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
