one.R-roller
R-roller Conveyor Chains have rollers with an outer diameter bigger compared to the width of plates.
Because the rollers can simply roll, the chain is ideal for running within the floor when the rollers get the dwell load.
2.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 obtain the force acting to the lateral sides of your chain, the chain is ideal for acquiring each a reside load plus a lateral load.
three.M-roller
M-roller Conveyor Chains have rollers with an outer diameter somewhat smaller than the width of plates.
An M roller is created for smoother engagement together with the sprockets. Since the chain is light in weight, it really is appropriate for vertical conveyance.
four.S-roller
S-roller Conveyor Chains have rollers with an outer diameter smaller than that of your M-roller.
The chain is suitable for vertical conveyance where rollers are significantly less prone to be worn.
5.BR- and BF- Rollers (with built-in bearings)
BR- and BF- Roller Conveyor Chains have typically identical construction to R-roller and F Conveyor Chains, respectively, except to the bearings within for smoother rotation.
six.UR- and UF- Rollers (huge clearance amongst bushing 
and roller)
UR- and UF- Roller Conveyor Chains have mostly identical structure to R-roller and F Conveyor Chains, respectively. Even so, the clearances involving the outer diameter of bushings and the inner diameter on the rollers are enlarged to avoid the rollers from repairing when foreign matters enter.
