TSUBAKI 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
