one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger compared to the width of plates.
Because the rollers can simply roll, the chain is ideal for working within the floor when the rollers obtain the live 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 obtain the force acting on the lateral sides from the chain, the chain is ideal for obtaining both a live load and also 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 built for smoother engagement with the sprockets. Since the chain is light in weight, it is appropriate for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that in the M-roller.
The chain is appropriate for vertical conveyance the place 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 construction to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
6.UR- and UF- Rollers (significant clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical framework to R-roller and F Conveyor Chains, respectively. Having said that, 
the clearances in between the outer diameter of bushings and also the inner diameter of your rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
