Wear Resistance Lead-Free Bimetal Bearing Bushes for Automobiles are specialized components designed to provide superior durability and performance in automotive applications. These bushings are constructed using a bimetal material that combines the wear resistance and strength of one metal with the lubrication and friction-reducing properties of another, all without the use of lead.
The bimetal material used in these bushings is carefully selected to offer optimal performance in automotive environments. It combines the hardness and durability of a high-strength metal with the lubricating characteristics of a softer alloy. This unique composition ensures that the bushings can withstand the high loads and speeds encountered in automotive applications while reducing friction and wear.
The lead-free design of these bushings is an important aspect that contributes to their environmental friendliness. Lead is a harmful material that can pose health risks and environmental concerns. By eliminating lead from the material composition, these bushings help to reduce the environmental impact of automotive manufacturing and use.
The high wear resistance of these bimetal bearing bushings ensures that they can maintain their performance over extended periods of operation. This durability is crucial in automotive applications, where components are subjected to constant wear and tear from various factors such as vibration, high temperatures, and friction.
In summary, Wear Resistance Lead-Free Bimetal Bearing Bushes for Automobiles are designed to provide superior durability, performance, and environmental friendliness in automotive applications. Their unique material composition and lead-free design make them an excellent choice for various automotive systems, contributing to the overall reliability and efficiency of the vehicle.

Advantage of Bimetal Bushings
low friction, high wear resistance
low coefficients of friction eliminate the
need for lubrication while reducing wear
and extending service life.
Maintenance-Free
Ideal for applications requiring long service
life without regular maintenance or operating
conditions with little or no lubrication.
Reduce shaft costs by eliminating the need
Lower System Cost
for hardening and machining grease paths.
Compact, one-piece construction provides
space and weight savings and simplifies
assembly.
Environmental
Greaseless, lead-free solutions comply
with increasingly stringent environmental
regulations such as the RoHS directive for
electrical and electronic equipment.
Bimetal Bushings Competitive Price,High Quality Standard SAE-797 bimetal bushing is based on steel and sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer. The strongest type of bimetal bushings and widely applicated in so many fields.
This type has the best performance within the range of Cu-Pb alloy constructured bushing.Thereforce it has a wide application and is mostly suitable for where is middle speed and high impact etc.
The bimetal bearing specialist with custom material manufacture
