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 conveniently roll, the chain is suitable for operating over the floor while the rollers obtain the reside load.
two.F-roller
F-roller Conveyor Chains have rollers with the similar outer diameter as that of R-roller but with flanges.
Because the flanges can receive 
the force acting about the lateral sides on the chain, the chain is suitable for acquiring both a dwell load in addition to 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 created for smoother engagement using the sprockets. Because the chain is light in weight, it can be appropriate for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of the M-roller.
The chain is suitable for vertical conveyance the place rollers are much less prone to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mostly identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
six.UR- and UF- Rollers (substantial clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical structure to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances among the outer diameter of bushings as well as the inner diameter on the rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
