one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger compared to 
the width of plates.
Because the rollers can conveniently roll, the chain is ideal for operating about the floor even though the rollers get the reside load.
2.F-roller
F-roller Conveyor Chains have rollers with the exact same outer diameter as that of R-roller but with flanges.
Because the flanges can receive the force acting around the lateral sides in the chain, the chain is appropriate for obtaining each a dwell load along with a lateral load.
3.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller than the width of plates.
An M roller is built for smoother engagement using the sprockets. Because the chain is light in fat, it can be appropriate for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of the M-roller.
The chain is appropriate for vertical conveyance wherever rollers are 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.
6.UR- and UF- Rollers (massive clearance among bushing and roller)
UR- and UF- Roller Conveyor Chains have typically identical construction to R-roller and F Conveyor Chains, respectively. Having said that, the clearances amongst the outer diameter of bushings as well as inner diameter of your rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
