one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter greater compared to the width of plates.
Since the rollers can very easily roll, the chain is appropriate for working within the floor although the rollers get the reside load.
two.F-roller
F-roller Conveyor Chains have rollers using the similar outer diameter as that of R-roller but with flanges.
Since the flanges can receive the force acting on the lateral sides with the chain, the chain is appropriate for acquiring the two a reside load and also a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized than the width of plates.
An M roller is created for smoother engagement together with the sprockets. Since the chain is light in excess weight, it is actually suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that on the M-roller.
The chain is ideal for vertical conveyance the place rollers are much less prone to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have generally identical structure to R-roller and F Conveyor Chains, respectively, except for that bearings inside for smoother rotation.
6.UR- and UF- Rollers (large clearance 
among bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively. However, the clearances between the outer diameter of bushings and also the inner diameter with the rollers are enlarged to stop the rollers from repairing when foreign matters enter.
