lubricating material

At the same time, the turn-around ring of the hammer head is made of special composite material, with the qualities of wear-resisting, self - lubricating, non-maintaining, easy changing etc.

Self-lubricating composite which possesses superior antifriction and wear resistance has been one of the central issues for advanced material research.

This means that rectorite is a good material for preparation of the thickening agent of lubricating grease and is a new high heat-resistance lubricating grease.
