R-roller Conveyor Chains have rollers with an outer diameter bigger than the width of plates.
Because the rollers can quickly roll, the chain is suitable for running within the floor though the rollers get the live load.
F-roller Conveyor Chains have rollers with the same outer diameter as that of R-roller but with flanges.
Because the flanges can get the force acting within the lateral sides of the chain, the chain is ideal for receiving the two a live load and also a lateral load.
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller compared to the width of plates.
An M roller is made for smoother engagement together with the sprockets. Because the chain is light in weight, it is actually appropriate for vertical conveyance.
S-roller Conveyor Chains have rollers with an outer diameter smaller sized than that from the M-roller.
The chain is suitable for vertical conveyance wherever rollers are less likely 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 for the bearings inside for smoother rotation.
six.UR- and UF- Rollers (massive clearance between bushing and roller)
UR- and UF- Roller Conveyor Chains have primarily identical framework to R-roller and F Conveyor Chains, respectively. However, the clearances amongst the outer diameter of bushings and the inner diameter with the rollers are enlarged to avoid the rollers from fixing when foreign matters enter.
