Super R-Lube® (SAE 863) self-lubricating powdered metal solid or cored bar products are harder and more wear-resistant that regular R-Lube®. The compositions consists of an iron base vs. a copper base, thus providing a stronger material.
Typical applications where Super R-Lube® may be used is for bearings or bushings that are used in heavy equipment and road machinery for example.
Typical Applications:
To manufacture bearings and bushings to required specifications.
