1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter greater than the width of plates.
Because the rollers can easily roll, the chain is appropriate for running around the floor while the rollers get the live load.
two.F-roller
F-roller Conveyor Chains have rollers using the identical outer diameter as that of R-roller but with flanges.
Because the flanges can get the force acting to the lateral sides of the chain, the chain is appropriate for obtaining each a dwell load along with 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. Because the chain is light in fat, it really 
is suitable for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that in the M-roller.
The chain is suitable for vertical conveyance exactly where 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 mainly identical construction to R-roller and F Conveyor Chains, respectively, except for your bearings inside for smoother rotation.
6.UR- and UF- Rollers (massive clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances in between the outer diameter of bushings along with the inner diameter in the rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
