one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Since the rollers can very easily roll, the chain is ideal for working about the floor whilst the rollers receive the live load.
2.F-roller
F-roller Conveyor Chains have rollers using the 
similar outer diameter as that of R-roller but with flanges.
Because the flanges can acquire the force acting about the lateral sides of the chain, the chain is ideal for receiving both a live load and a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller sized than the width of plates.
An M roller is developed for smoother engagement with the sprockets. Since the chain is light in excess weight, it is appropriate 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 ideal for vertical conveyance the place rollers are less more likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mainly identical framework to R-roller and F Conveyor Chains, respectively, except for the bearings within for smoother rotation.
six.UR- and UF- Rollers (huge clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical structure to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances among the outer diameter of bushings plus the inner diameter from the rollers are enlarged to avoid the rollers from repairing when foreign issues enter.
