1.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Because the rollers can quickly roll, the chain is suitable for operating within the floor while the rollers get the dwell load.
2.F-roller
F-roller Conveyor Chains have rollers with all 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 of your chain, the chain is appropriate for getting the two a live load along with a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter slightly smaller sized than the width of plates.
An M roller is made for smoother engagement with the sprockets. Because the chain is light in fat, it can be suitable for vertical conveyance.
four.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 prone to 
be worn.
five.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 for the bearings inside for smoother rotation.
six.UR- and UF- Rollers (substantial clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have mainly identical framework to R-roller and F Conveyor Chains, respectively. However, the clearances among the outer diameter of bushings along with the inner diameter in the rollers are enlarged to avoid the rollers from repairing when foreign issues enter.
