one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Since the rollers can conveniently roll, the chain is appropriate for operating on the floor even though the rollers get the dwell 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.
Because the flanges can obtain the force acting to the lateral sides from the chain, the chain is suitable for obtaining each a dwell load as well as a lateral load.
three.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 made for smoother engagement together with the sprockets. Because the chain is light in excess weight, it can be suitable for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that from the M-roller.
The chain is appropriate for vertical conveyance wherever rollers are less likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have generally identical construction to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
six.UR- and UF- Rollers (big clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical structure to R-roller and F Conveyor Chains, respectively. Having said that, the clearances between the outer diameter of bushings and the inner diameter of the rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
