one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter more substantial compared to the width of plates.
Because the rollers can conveniently roll, the chain is appropriate for working within the floor though the rollers receive the dwell load.
2.F-roller
F-roller Conveyor Chains have rollers using the exact same outer diameter as that of R-roller but with flanges.
Because the flanges can obtain the force acting to the lateral sides on the chain, the chain is ideal for acquiring the two a dwell load along with a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller sized compared to the width of plates.
An M roller is created for smoother engagement using the sprockets. Because the chain is light in fat, it truly is appropriate for vertical conveyance.
4.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is appropriate for vertical conveyance in which rollers are much less prone to be worn.
five.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have mainly identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
6.UR- and UF- Rollers (huge clearance involving bushing and roller)
UR- and UF- Roller Conveyor Chains have largely identical construction to R-roller and F Conveyor Chains, respectively. Nonetheless, the clearances concerning the outer diameter of bushings as well as the inner diameter of your rollers are enlarged to avoid the rollers from 
repairing when foreign matters enter.
