1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can easily roll, the chain is ideal for operating to the floor when 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.
Since the flanges can obtain the force acting around the lateral sides on the chain, the chain is ideal for obtaining each a live load as well as a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized compared to the width of plates.
An M roller is built for smoother engagement with all the sprockets. Because the chain is light in fat, it is appropriate for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that from the M-roller.
The chain is ideal for vertical conveyance 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 generally identical construction to R-roller and F Conveyor Chains, respectively, except for your bearings within for smoother rotation.
six.UR- and UF- Rollers (substantial clearance amongst bushing and roller)
UR- and UF- Roller Conveyor Chains have typically identical framework to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances involving the outer diameter of bushings and also the inner diameter of the rollers are enlarged to prevent the rollers from fixing when foreign issues enter.
