1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter larger than the width of plates.
Because the rollers can very easily roll, the chain is suitable for operating over the floor while the rollers obtain the reside load.
2.F-roller
F-roller Conveyor Chains have rollers with the similar outer diameter as that of R-roller but with flanges.
Because the flanges can acquire the force acting on the lateral sides with the chain, the chain is appropriate for obtaining both a dwell load plus a lateral load.
three.M-roller
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. Since the chain is light in weight, it is ideal for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is suitable for vertical conveyance exactly where rollers are less likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have primarily identical structure 
to R-roller and F Conveyor Chains, respectively, except for your bearings within for smoother rotation.
six.UR- and UF- Rollers (massive clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical framework to R-roller and F Conveyor Chains, respectively. Nevertheless, the clearances between the outer diameter of bushings as well as inner diameter of your rollers are enlarged to prevent the rollers from fixing when foreign issues enter.
