one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial than the width of plates.
Since the rollers can conveniently roll, the chain is suitable for running over the floor whilst the rollers acquire the live load.
two.F-roller
F-roller Conveyor Chains have rollers with the very same outer diameter as that of R-roller but with flanges.
Because the flanges can get the force acting on the lateral sides with the chain, the chain is suitable for acquiring both a live load and a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized than the width of plates.
An M roller is designed for smoother engagement using the sprockets. Because the chain is light in bodyweight, it’s suitable for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that in the M-roller.
The chain is appropriate 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 typically identical framework 
to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
six.UR- and UF- Rollers (big clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have generally identical structure to R-roller and F Conveyor Chains, respectively. Having said that, the clearances concerning the outer diameter of bushings plus the inner diameter from the rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
