one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger compared to the width of plates.
Because the rollers can conveniently roll, the chain is suitable for working to the floor while the rollers acquire the dwell load.
two.F-roller
F-roller Conveyor Chains have rollers using the similar outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting on the lateral sides of your chain, the chain is suitable for receiving the two a live load as well as a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller sized compared to the width of plates.
An M roller is developed for smoother engagement using the sprockets. Because the chain is light in weight, it truly is suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that from the M-roller.
The chain is suitable for vertical conveyance wherever rollers are significantly less likely to be worn.
5.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 for your bearings within for smoother rotation.
six.UR- and UF- Rollers (substantial clearance between 
bushing and roller)
UR- and UF- Roller Conveyor Chains have mostly identical construction to R-roller and F Conveyor Chains, respectively. Even so, the clearances involving the outer diameter of bushings and also the inner diameter with the rollers are enlarged to stop the rollers from repairing when foreign matters enter.
