one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Since the rollers can very easily roll, the chain is appropriate for working around the floor even though the rollers get the dwell load.
two.F-roller
F-roller Conveyor Chains have rollers together with the similar outer diameter as that of R-roller but with flanges.
Since the flanges can get the force acting within the lateral sides of the chain, the chain is ideal for acquiring both a dwell load in addition to a lateral load.
3.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 all the sprockets. Since the chain is light in weight, it really is ideal for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that in the M-roller.
The chain is ideal for vertical conveyance exactly where rollers are significantly less more likely to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mainly identical framework to R-roller and F Conveyor Chains, respectively, except for your bearings inside for smoother rotation.
6.UR- and UF- Rollers (huge clearance in between bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical framework to R-roller and F Conveyor Chains, respectively. However, the clearances in between the outer diameter of bushings and also the inner diameter in 
the rollers are enlarged to avoid the rollers from repairing when foreign matters enter.
