1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter greater compared to the width of plates.
Because the rollers can simply roll, the chain is suitable for running to the floor though the rollers receive the dwell load.
2.F-roller
F-roller Conveyor Chains have rollers with all the same outer diameter as that of R-roller but with flanges.
Because the flanges can get the force acting about the lateral sides in the chain, the chain is appropriate for obtaining each a live load and also a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller than the width of plates.
An M roller is made for smoother engagement with all the sprockets. Since the chain is light in weight, it’s appropriate for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that from the M-roller.
The chain is ideal for vertical conveyance wherever rollers are less prone to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical framework to R-roller and F Conveyor Chains, respectively, except for that bearings within for smoother rotation.
six.UR- and UF- Rollers (massive clearance among bushing and roller)
UR- and UF- Roller Conveyor Chains have primarily identical structure to R-roller and F Conveyor Chains, respectively. Even so, the clearances among the outer diameter of bushings plus the inner diameter with the rollers are enlarged to avoid the rollers from repairing when foreign matters enter.
