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 operating within the floor although the rollers get the dwell load.
2.F-roller
F-roller Conveyor Chains have rollers with the similar outer diameter as that of R-roller but with flanges.
Since the flanges can receive the force acting within the lateral sides in the chain, the chain is appropriate for getting the two a live load in addition to 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 developed for smoother engagement using the sprockets. Because the chain is light in bodyweight, it’s appropriate for vertical conveyance.
four.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 much less more likely to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical structure to R-roller and F Conveyor Chains, respectively, except to the bearings inside for smoother rotation.
6.UR- and UF- Rollers (huge clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical framework to R-roller and F Conveyor Chains, respectively. Even so, the clearances involving the outer diameter of bushings plus the inner diameter with the rollers are enlarged to avoid the rollers from fixing when foreign issues enter.
