Product Description

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.
