Bimetal Bushing Manufactuer,VIIPLUS.COM is the professional manufacture and sale of oilless lubncation bearings.The company to rely on technological progress, the use of advanced process, introduced advanced equlpment; committed to the purpose of lubncation bearings is oilless and the development of new materials developed different areas.

Bimteal Bearing Bushings material,The right material for your application.

The performance of plain bearings depends largely on the materials used and the load generated.In contrast to rolling bearings, there is no rolling motion, but sliding motion.Thus, the task of the sliding bearing material is to produce as little friction as possible in relation to the sliding partner, to absorb impact, to be insensitive to dirt, not to wear, and to be as cheap as possible.

Unfortunately, no single material can meet all the requirements.Therefore, designers must choose materials suitable for their respective applications.We offer a wide selection of different materials and plain bearings that can be made from.We are happy to help you make the right choice.


Viiplus offers a broad range of sizes, forms, and materials in bimetallic bearings. Bimetal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine, and offshore environments. Viiplus bearings can be made in many sizes and forms, including thin-walled, thick-walled, flanged, cylindrical, sintered and oil-impregnated, and more.

Technical information on the datasheet.

Bimetal-bearing is a bimetal bearing, wrapped of steel sheets with a layer of lead bronze.

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.

Material Structure

Metal backed with bronze graphite oilless bearings

1. Sinter bronze with graphite– Liner material: CuPb10Sn10.Good wear resistance with lower friction and excellent load-carrying capacity. The bimetallic bushing can be machined after fitting to get precision tolerance. We also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.

2. Metal backing –low carbon steel: gives exceptionally high load carrying capacity, excellent heat dissipation.

3. Copper plating 0.002mm, good corrosion resistance.

Due to the stability of the matrix is low carbon steel material, the machining accuracy of the outer diameter of the shaft sleeve is guaranteed, and there is no need for screw fixation after the product is loaded into the seat hole, so the interference fit can prevent the phenomenon of going round outside. The change of chemical composition of the inner surface alloy layer can meet the requirements of different bearing pressure, different service temperatures, and different sliding speeds. An oil grooves and oil holes with different structures can meet the requirements of different refueling methods and prevent the phenomenon of the biting shaft.

The bimetallic bearing has the advantages of good wear resistance, especially suitable for medium speed, medium load, and low speed and high load. Various oil slots, oil holes, and oil holes can be machined on the friction surface by special technological means, so as to adapt to the use under different lubrication conditions. The products are mainly used in the balance bridge bushing and gasket of heavy vehicles. Automobile engine, chassis, motorcycle clutch, gear pump wipe plate, and lifting equipment, and other fields.

Types for Bi-Metallic Bushing’s Grooves and Indents


1. Standard cylindrical bushing, flanged bimetal bearing, thrust washers, and strips are available.
2. Special designed bimetal bearings are produced at short notice
3. Alloy material CuSn6Zn6Pb3 is also available


The special structure of this type of self-lubricating bearing is suitable for hostile environments, for high load application which lubrication is difficult.  bimetallic bush has been widely used in water turbines, vane controls, injection molding machinery, packing machines, construction equipment, tire molds, paper production machinery, furnace expansion plates, automotive transmission, heavy lifting chain linkage, food production equipment, etc.


Steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties. It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, tailgate pivots, mechanical handling and lifting equipment, hydraulic motors, agricultural machinery etc.
