one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Because the rollers can easily roll, the chain is ideal for working within the floor although the rollers acquire the dwell load.
two.F-roller
F-roller Conveyor Chains have rollers together with the same outer diameter as that of R-roller but with flanges.
Since the flanges can receive the force acting about the lateral sides with the chain, the chain is ideal for acquiring the two a live load as well as a lateral load.
three.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 together with the sprockets. Because the chain is light in bodyweight, it’s appropriate 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 where rollers are much less more likely to be worn.
5.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 (significant clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical framework to R-roller and F Conveyor Chains, respectively. Nevertheless, the clearances involving the outer diameter of bushings and also the inner diameter on the rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
