R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Because the rollers can conveniently roll, the chain is ideal for operating over the floor while the rollers get the dwell load.
F-roller Conveyor Chains have rollers with the very same outer diameter as that of R-roller but with flanges.
Since the flanges can obtain the force acting to the lateral sides from the chain, the chain is appropriate for getting each a dwell load and also 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 with all the sprockets. Since the chain is light in excess weight, it’s appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that from the M-roller.
The chain is suitable for vertical conveyance in which rollers are much less prone to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have largely identical framework to R-roller and F Conveyor Chains, respectively, except for the bearings inside for smoother rotation.
6.UR- and UF- Rollers (big clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have typically identical framework to R-roller and F Conveyor Chains, respectively. Having said that, the clearances between the outer diameter of bushings plus the inner diameter on the rollers are enlarged to avoid the rollers from fixing when foreign issues enter.
