Cylindrical Wrapped Bronze Bushings
The bronze bushing has excellent wear resistance with lower friction & high level of thermal conductivity, also with excellent chemical stability, suitable for rough conditions. It can play optimum performance under relatively high loads and low speeds. The item can also be composed in steel housing or fabricaed into flanged bushes which both outer surface and inside bore can be used as working surface.This material of wear plate can be applied in sliding part of bridge surporter instead of PTFE plate,and it can reach the requirement of load capacity of 140N/mm2.
1. Product Description
Cylindrical Bushings Grease Bronze Sleeve Plain Bearings Cusn8P Oilless are made of bronze base,sinter with bronze powder and PTFE layer wih filling material of anti-high temperature. It has high safety factor and is particularly appropriate for high temperature environment where no oil is effcient and where he machine must be under successive long period working condition.
