R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can conveniently roll, the chain is suitable for running on the floor while the rollers get the dwell load.
F-roller Conveyor Chains have rollers using the very same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting on the lateral sides of the chain, the chain is ideal for getting the two a reside load along with a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller compared to the width of plates.
An M roller is designed for smoother engagement using the sprockets. Since the chain is light in fat, it is appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that from the M-roller.
The chain is appropriate for vertical conveyance where rollers are much less likely to be worn.
five.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 for that bearings inside for smoother rotation.
6.UR- and UF- Rollers (huge clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have largely 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.
