R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Since the rollers can very easily roll, the chain is ideal for working around the floor whilst the rollers obtain the dwell load.
F-roller Conveyor Chains have rollers with the exact same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting within the lateral sides on the chain, the chain is appropriate for receiving the two a dwell load in addition to a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized compared to the width of plates.
An M roller is developed for smoother engagement together with the sprockets. Because the chain is light in fat, it is actually ideal for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is appropriate for vertical conveyance where rollers are less more likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mostly identical framework to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
6.UR- and UF- Rollers (large clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical structure to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances involving the outer diameter of bushings as well as inner diameter on the rollers are enlarged to avoid the rollers from repairing when foreign issues enter.
