Bearing roller conveyor chain  Standard Lube Free Series

Product photo
  • Uses special cylindrical bearings that provide self-lubricating functions between bushes and rollers -- rollers can be used without additional lubrication.
  • Available with EBR or EBF rollers.
  • Be advised when selecting that Lube-free Series has a different maximum allowable load than Standard Series. Roller allowable load is same.
  • Operating Ambient Temperature :-20℃~50℃

※Maximum allowable load is a value calculated based on Tsubaki in-house standards and is calculated strength. As long as there are no other constraints, maximum allowable load is used in selecting large size conveyor chain.
This value will differ by manufacturer and is not a guaranteed value.

※Contact a Tsubaki representative regarding average tensile strength.
