Aluminium Tin Alloy Bushing Babbit Bushes Excavator Hydraulic Cylinder Du Bushing, Sleeve Bush, Du Dry Bushing
This bimetal bearing is a type of aluminium tin alloy based bimetal bushing. This type self lubricating bearing has common structure with other bimetal bushes.
Structure:
Low carbon steel + aluminium tin alloy(AlSn20Cu)
Characteristics:
Suitable for medium fatigue-resistance, good load capacity
good corrosion-resistance and super surface property, smooth sliding movement
Application:
This bimetal bush is widely used in engine bearing with middle or low power, air compressor bushing. And it is a good substitution for Babbit material.
