one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Since the rollers can simply roll, the chain is appropriate for operating about the floor while the rollers receive the live load.
two.F-roller
F-roller Conveyor Chains have rollers with the same outer diameter as that of R-roller but with flanges.
Since the flanges can get the force acting about the lateral sides in the chain, the chain is ideal for receiving both a dwell load as well as 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. Since the chain is light in bodyweight, it is suitable 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 appropriate for vertical conveyance wherever rollers are much less likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
six.UR- and UF- Rollers (huge clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have primarily identical framework to R-roller and F Conveyor Chains, respectively. Having said that, the clearances concerning the outer diameter of bushings and the inner diameter in the rollers are enlarged to avoid the rollers from repairing when foreign issues enter.
