1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger than the width of plates.
Since 
the rollers can easily roll, the chain is suitable for working on the floor while the rollers obtain the reside load.
2.F-roller
F-roller Conveyor Chains have rollers using the very same outer diameter as that of R-roller but with flanges.
Since the flanges can acquire the force acting about the lateral sides from the chain, the chain is suitable for obtaining both a reside load plus a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller than the width of plates.
An M roller is built for smoother engagement with all the sprockets. Because the chain is light in fat, it really is 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 ideal for vertical conveyance exactly where rollers are much less prone 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 (substantial clearance concerning bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical construction to R-roller and F Conveyor Chains, respectively. Having said that, the clearances involving the outer diameter of bushings as well as inner diameter in the rollers are enlarged to prevent the rollers from repairing when foreign issues enter.
