Product Description

OEM Customized Leaf Spring Bushing Bimetal Bushing Bearing Car Bushes, Steel Backed Plain Bronze, China Supply Factory


Precision Bimetal Bushing manufacturer,DIN-G-CuPb24Sn4 / Steel Bronze Bimetal bushing & strips and prefessional plain bearings supplier,Sintered SAE799 Layer + Steel Backing + Copper Plating / Tin-Plating, Material CuPb24Sn4, SAE-799 Bimetal Bronze Alloy Bearings china maunfacturer.

The sleeve steel bronze bushings & bearings 720 made to order from china are bimetal sliding bearings with a steel strip and sintered CuPb24Sn4 as the surface sliding layer. Thanks to their high performance characteristics, long service lives at low material fatigue and high levels of load capacity, they are suitable for medium speeds and loads. The bushes-720 sliding bearings are used in the construction and agricultural machinery industries.

Bimetal Sleeve Bushings Consists of a high quality low carbon steel backing carring a sintered tin-lead-bronze alloy (CuSn4Pb24) as a sliding layer. In order to improve tribological behavior the sliding layer can be machined with lubricating grooves for oil- or grease storage and distribution. In case of corrosive environment the backing can be copper plated. BIMETAL sleeve Bushings is used for wrapped bushes, thrust washers and bushes in connecting rods of gas engines, etc.

  • Sliding layer can be machined with lubricating grooves and/or with grease indents

  • steel backing can be copper plated

  • Steel+CuPb24Sn4

Bimetal Bearing Bushes.



It is backed with high quality low carbon steel with tin-lead-bronze alloy (CuSn4Pb24) sintered on its surface.To effectively decrease abrasion, its alloy surface can be machined with oil grooves for easier oil storage. When necessary, an erosion protection coating can be plated on the steel back. In common use, BIMETAL BUSHINGS is made to wrapped bushes,thrust washer and bushes on connecting rod level of gas engine, etc

JF720 Bi-METAL Steel backing with CuPb24Sn4 liner, with good fatigue strength and sliding performance. Primarily applied to fully lubricated connecting rod or main bushings in engines and compressors.Bimetal Bearing & Bushing (SAE799, CuPb24Sn4 material JF-720)

The 720 Bimetal sleeve bushings are bimetal sliding bearings with a steel strip and sintered CuPb24Sn4 as the surface sliding layer.

Bimetal bushings high performance characteristics, long service lives at low material fatigue and high levels of resilience, they are suitable for medium speeds and loads. The 720 steel bronze sleeve sliding bearings are used in the construction and agricultural machinery industries.

Bimetal boundary lubricated rolling bearing is a key component of heavy equipment.VIIPLUS from China is located in jiashan county, zhejiang province, which is the national production base of self-lubricating bearing, bimetal boundary lubrication rolling bearing.With the recovery of the construction machinery industry, the demand from this industry increases sharply, which directly leads to the increase of the demand for self-lubricating bimetal bearings & bushings.The U.S. 's GGB, sankyo oilless and DAIDO are the world's top three makers of self-lubricated bearings, with strong positions in aerospace, automotive and transportation.VIIPLUS also established itself as an industry leader in self-lubricating bearings exported from China.

It is the main product, it has excellent mechanical bearing capacity, especially suitable for the working conditions of non-refueling and non-refueling.In addition, it has low maintenance costs and is corrosion resistant, so it is often installed in large quantities in key parts of tracked heavy equipment.

Jf-720 CuPb24Sn Bimetal Metal Bushing


Jf-720 bimetallic bearing is a product of CuPb24Sn4 alloy sintered on the surface of steel plate.The product has good fatigue strength and bearing capacity.Suitable for medium speed, medium load and oil lubrication.When the surface is plated with soft alloy, it can be used as the bearing and connecting rod bushing of high-speed internal combustion engine to achieve good wear resistance and fatigue resistance.

Because the matrix is stable as low carbon steel material, so the machining accuracy of the outer diameter of the shaft sleeve has been guaranteed, and there is no need for screw fixation after the product is loaded into the seat hole, relying on interference fit can prevent the phenomenon of going out of the circle.The change of chemical composition of inner surface alloy layer can meet the requirements of different bearing pressure, different service temperature and different sliding speed. The oil groove and oil hole with different structure are designed in the production of friction surface to meet the requirements of different ways of oil adding, prevent shaft biting and adapt to different lubrication conditions.
Widely used in automobile engine, motorcycle clutch, light industrial machinery, construction machinery.
Alloy layer material CuPb10Sn10 or CuSn6Zn6Pb3



Bimetal bearing 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.

Typical Characteristics

Suitable for low speed, heavy load or intermittent movement conditions, lubricating oil film can not form or maintain the occasion;
Suitable for working environment or mechanical structure restrictions, it is difficult to supply oil lubrication occasions;
It is suitable for rotating, reciprocating, swinging, linear and other forms of movement, as well as occasions requiring frequent starting or starting under high load;
Suitable for high or low temperature work, or the environment temperature range of large occasions;Good corrosion resistance, can be used in seawater and other corrosive media such as chemical liquids or gases, as well as water containing sediment or radioactive environment;
Non-water absorption, good dimensional stability, high mechanical strength, good thermal conductivity;
Bearing is thin wall structure, light weight, small volume, suitable for compact design;
Compared with the traditional three-layer composite material, the static load characteristics, wear-resistance, service temperature, dimensional stability and so on under the condition of non-grease lubrication are better;
Compared with copper inlaid self-lubricating material, it is more suitable to work under the condition of small Angle swing, and the price is cheaper.

This product is the most powerful bearing capacity in the double-alloy bearing, the balance bridge bushing and gasket of heavy vehicles;Driven wheel and supporting wheel of bulldozer;Automobile steel plate bushing, USES this product.It is a kind of high load and low speed sliding bearing widely used.


Agricultural Machinery

As the self-lubricating bearing has the characteristics of maintenance-free and good abrasion resistance under dust and outdoor conditions, it is widely used in the cylinder, suspension system of combine harvester, planter, baler, crusher, tractor, Joints and other parts can not be difficult to form oil or oil film parts.
bushing application

  • Fork lifts

  • Pallet Trucks

  • Cranes

  • Excavators


  • For high load capacity and oscillating movement, as well as for rough operation and temperature load. Long-run lubrication because of lubricant storage.

Tolerance Details

  • Housing ØH7

  • Bushing inner-Ø after mountingH9

  • Shaft tolerancef7 to h8


  • is a low-maintenance composite sliding bearing, but primary lubrication is necessary. Oil or grease lubrication is possible. Due to solid lubricant storages, lubrication clearances are reduced to a minimum!
