1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial than the width of plates.
Since the rollers can effortlessly roll, the chain is suitable for operating around the floor when the rollers obtain the reside load.
2.F-roller
F-roller Conveyor Chains 
have rollers with all the exact same outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting to the lateral sides in the chain, the chain is appropriate for receiving the two a reside load and also a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller sized than the width of plates.
An M roller is designed for smoother engagement with the sprockets. Because the chain is light in excess weight, it’s suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is appropriate for vertical conveyance wherever rollers are significantly less more likely 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 for that bearings within for smoother rotation.
6.UR- and UF- Rollers (big clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical structure to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances involving the outer diameter of bushings and the inner diameter of the rollers are enlarged to avoid the rollers from fixing when foreign issues enter.
