1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger compared to the width of plates.
Since the rollers can easily roll, the chain is ideal for running within the floor while the rollers receive the dwell load.
two.F-roller
F-roller Conveyor Chains have rollers with the identical outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting about the lateral sides of your chain, the chain is ideal for acquiring both a live load and a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller compared to the width of plates.
An M roller is designed for smoother engagement with all the sprockets. Because the chain is light in bodyweight, it can be ideal for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter 
smaller sized than that on the M-roller.
The chain is ideal for vertical conveyance wherever rollers are significantly less prone to be worn.
five.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.
six.UR- and UF- Rollers (large 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 between the outer diameter of bushings as well as inner diameter of the rollers are enlarged to avoid the rollers from repairing when foreign issues enter.
