1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can quickly roll, the chain is suitable for running within the floor although the rollers get the live load.
2.F-roller
F-roller Conveyor Chains have rollers with all the very same outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting to the lateral sides of your chain, the chain is ideal for getting both a live load along with a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller than the width of plates.
An M roller is made for smoother engagement with the sprockets. Since the chain is light in excess weight, it’s suitable for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that of the M-roller.
The chain is ideal for vertical conveyance the place rollers are less likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- 
and BF- Roller Conveyor Chains have mainly identical structure to R-roller and F Conveyor Chains, respectively, except for your bearings within for smoother rotation.
6.UR- and UF- Rollers (big clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have mostly identical construction to R-roller and F Conveyor Chains, respectively. On the other hand, the clearances concerning the outer diameter of bushings as well as the inner diameter of your rollers are enlarged to stop the rollers from repairing when foreign matters enter.
