1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Since the rollers can very easily roll, the chain is ideal for operating within the floor though the rollers receive the reside load.
two.F-roller
F-roller Conveyor Chains have rollers with the exact same outer diameter as that of R-roller but with flanges.
Since the flanges can acquire the force acting around the lateral sides with the chain, the chain is ideal for receiving each a reside load and a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller sized compared to the width of plates.
An M roller is created for smoother engagement together with the sprockets. Since the chain is light in weight, it really is suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that in the M-roller.
The chain is appropriate for vertical conveyance in which rollers are significantly less more likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have largely identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
six.UR- and UF- Rollers (massive clearance amongst bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical construction to R-roller and F Conveyor Chains, 
respectively. On the other hand, the clearances concerning the outer diameter of bushings along with the inner diameter from the rollers are enlarged to prevent the rollers from fixing when foreign matters enter.
