Bimetallic bearing bushings for vehicles, specifically CuPb10Sn10 or CuSn6Zn6Pb3 alloys, are designed to provide superior performance in automotive applications. These bushings consist of a base metal layer bonded to a wear-resistant alloy layer, creating a unique bimetallic construction.
The CuPb10Sn10 alloy, also known as leaded tin bronze, offers excellent wear resistance and lubricity. The lead content provides self-lubricating properties, reducing friction and wear during operation. This alloy is commonly used in automotive bushings and bearings where smooth and reliable operation is crucial.
The CuSn6Zn6Pb3 alloy, also known as high-lead tin bronze, exhibits similar properties to CuPb10Sn10 but with a slightly different composition. It provides excellent wear resistance, lubricity, and corrosion resistance, making it suitable for demanding automotive applications.
The bimetallic construction of these bushings combines the strength and durability of the base metal with the wear resistance and self-lubricating properties of the alloy layer. This ensures smooth operation, reduced maintenance requirements, and extended service life in various vehicle applications.
Our range of bimetallic bearing bushings for vehicles includes CuPb10Sn10 and CuSn6Zn6Pb3 alloys in various sizes and specifications to meet your specific requirements. We offer customized solutions to ensure the perfect fit and performance for your automotive application.

Model: 800 bimetallic bearings
The bimetal bearing is made of high-quality low carbon steel, and its inner surface is sintered with a bronze alloy layer and
rolled with a hemispherical oil hole, which is convenient for oil
storage and can effectively reduce wear. The outer surface of the
product can be selected as natural color, copper-plated, or
tin-plated according to the demand. This product is one of the
bearing capacity of double alloy bearings. It is widely used in
balancing bridge bushings of heavy vehicles. It is a kind of high
load and low-speed motion bearings with wide applications.
JF bimetal composite bearings with high-quality low carbon steel as substrate, the surface of the sinter with low friction
properties of copper alloy (CuPb10Sn10 CuPb6Sn6Zn3 CuPb24Sn4,
CuPb30, AlSn20Cu, CuSn8Ni) as a wear-resisting layer of bearing,
can need according to the operating conditions of copper alloy
surface processing of various types of the oil tank, oil hole,
hole, etc., in order to suit to cannot continue to go hard or go
occasion. The material can obtain good bonding strength and the
best bearing capacity through two times sintering and two times
extrusion.
Construction machinery: chassis walking mechanism supporting wheel
shaft cover, towing wheel shaft cover, tensioning wheel shaft
cover; Automotive industry: balance bushing, steel plate pin
bushing, steering knuckle main Shaw bushing, connecting rod
bushing, valve rocker arm bushing, camshaft bushing, differential
bushing, gearbox bushing, internal combustion engine spindle bush,
thrust gasket; And piston pump side plate, gear pump side plate,
etc.
Bimetallic bearings to the high-quality low-carbon steel substrate, the surface of the sintered copper alloy having a low friction characteristic (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30,
AlSn20Cu, CuSn8Ni) as a wear layer bearing copper alloy surfaces
can be processed in accordance with the use of a variety of
conditions need type tank, oil hole, oil hole, so as to fit in
unsustainable fuel refueling or difficult situations. Secondary
extrusion material through the secondary sintering can be a good bonding strength and optimum carrying capacity.

The standard sizes are fitted with lubrication indents on the running surface. For standard bearings is normally the steel backing copper plated
to improve the corrosion resistance. The layer of lead bronze makes it possible to use these bearings
with relatively long lubrication intervals.
Bimetal-bearings can be manufactured with a thicker lead bronze layer for
applications where the bearing has to be machined after mounting.
The material of the layer can be fitted to the special needs of the
application in question.
