one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter greater than the width of plates.
Because the rollers can very easily roll, the chain is suitable for 
running around the floor although the rollers receive the live load.
two.F-roller
F-roller Conveyor Chains have rollers together with the identical outer diameter as that of R-roller but with flanges.
Because the flanges can acquire the force acting within the lateral sides with the chain, the chain is appropriate for acquiring both a reside load along with a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller than the width of plates.
An M roller is intended for smoother engagement using the sprockets. Because the chain is light in bodyweight, it truly is ideal for vertical conveyance.
4.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 wherever rollers are less more likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have generally identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
6.UR- and UF- Rollers (significant clearance among bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical construction to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances among the outer diameter of bushings and also the inner diameter of the rollers are enlarged to prevent the rollers from repairing when foreign matters enter.
