1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger than the width of plates.
Because the rollers can simply roll, the chain is suitable for operating on 
the floor whilst the rollers get the dwell load.
two.F-roller
F-roller Conveyor Chains have rollers with the same 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 ideal for acquiring each a dwell load plus a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller compared to the width of plates.
An M roller is created for smoother engagement together with the sprockets. Because the chain is light in weight, it is ideal for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is suitable for vertical conveyance in which rollers are less likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have primarily identical structure to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
6.UR- and UF- Rollers (substantial clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances between the outer diameter of bushings and the inner diameter of your rollers are enlarged to prevent the rollers from fixing when foreign issues enter.
