  • Bearing Roller Conveyor Chain

Lube-free Series Standard Specifications

Uses special cylindrical bearings that provide self-lubricating functions between bushes and rollers -- rollers can be used without additional lubrication.

Be advised when selecting that the Lube-free Series has a different maximum allowable load than the Standard Series. The roller allowable load is the same.

Available with EBR or EBF rollers.

Operating temperature range: -20ºC to 50ºC
