Boundary Lubrication Bushing is composed of three layers: steel backing, sintered bronze layer and


modified POM layer. It fits well for low speed, high load, normally temperature occasions with rotational,


oscillating or frequent stop-start motion. It can work long time under boundary lubrication circumstances, if


oil or grease is add, its working life can be prolonged further.
