one.R-roller
R-roller Conveyor Chains have rollers with 
an outer diameter more substantial than the width of plates.
Since the rollers can simply roll, the chain is ideal for operating about the floor although the rollers get the dwell load.
2.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 acquire the force acting to the lateral sides from 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 slightly smaller than the width of plates.
An M roller is developed for smoother engagement using the sprockets. Because the chain is light in fat, it is actually appropriate for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of the M-roller.
The chain is suitable for vertical conveyance exactly where rollers are less prone to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have generally identical construction to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
6.UR- and UF- Rollers (large clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical construction to R-roller and F Conveyor Chains, respectively. Having said that, the clearances in between the outer diameter of bushings and the inner diameter with the rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
