SAE799 Bimetal Bearing Bushes made of Sintered CuPb24Sn4 Material, JF-720 Plain Bearing refers to a type of bearing bushing that is constructed from a bimetal material, specifically a sintered copper alloy containing 24% lead (Pb) and 4% tin (Sn). The SAE799 standard designates certain requirements and specifications for this type of bimetal bearing.

JF-720 is a plain bearing designation, indicating that this bushing is a non-lubricated, low-friction component designed to support radial or axial loads. The sintered CuPb24Sn4 material provides excellent wear resistance, fatigue strength, and conformability, making it suitable for a wide range of applications.

Bimetal bearings are often used in automotive, industrial, and other applications where there is a need for high load capacity, good wear resistance, and low maintenance. The combination of copper, lead, and tin in the sintered alloy results in a material that is both strong and ductile, allowing it to conform to mating surfaces and distribute loads evenly.

When selecting SAE799 bimetal bearing bushes for a specific application, it is important to consider the required dimensions, tolerances, and operating conditions to ensure that the bushings will perform as expected. Additionally, proper installation and maintenance procedures should be followed to maximize the service life of the bearings.

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

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

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
