Because FGM have special excellent properties, their application scope gradually enlarges to the structure materials for mechanical engineering such as self lubricating sliding bearings, cemented carbide cutting tools and coating materials resistant wear and corrosion.

PTFE-bronze powder-steel is a widely used three-layer self-lubricating bearing material with good anti-friction and anti-wear.

This paper introduces the selection and disposal modes of the common planet gear bearing, analyzes the application advantages of cylindrical roller and self-lubricating bearing, and advances some effective approaches on solving the technological difficulties of the design of planet gear bearing with small diameter.

Through the problem analysis of bearing on the shea rer walk gear, that a ppeared on the run, introduces a property of self-lubricating bearing and use in the place of shearer walk gear, in the meantime list notice problem bearing in p rocess of us

Advance in Research and Development of Self-lubricating Composite Used by Bearing Materials in China;

New composite materials for metal-based self-lubricating bearing are classified into powder-metallurgy types including Fe-based,copper-based,Zn-based and Ni based,and surface-engineering types including Fe-based,Cu-based,Zn-based,Ti-based.

The friction and wear tests of the self lubricating bearing made of carbon fiber reinforced copper matrix composite materials are arranged by uniform design that can greatly reduce the test duration.
