What are the specific applications of JF series bimetallic bearings?

‌JF bimetallic bearings are a high-performance composite material bearing with low-carbon steel plate as the matrix and copper alloy sintered on the surface as the wear-resistant layer‌.
The JF bimetallic bearings produced by Zhejiang Mingxu Machinery Manufacturing Co., Ltd. include various models, such as JF-800, JF700, JF20, etc. Their main difference lies in the different copper alloy materials sintered on the surface, such as CuPb10Sn10, CuPb30, AISn20Cu, etc.
Under ideal working conditions and with proper maintenance measures, the service life of JF bimetal bearings can be as long as 5 to 10 years, or even longer.

‌Features
These bearings combine the advantages of steel and copper alloys, with high load-bearing capacity, good wear resistance, corrosion resistance and low friction coefficient.

• Low cost‌: Compared with copper sleeves, babbitt alloys, and roller bearings, the cost is lower.
• Good wear resistance‌: It has good wear resistance and long service life.
• Strong load-bearing capacity‌: The load-bearing capacity is strong among bimetallic bearings, suitable for heavy vehicles, bulldozers, etc.
• Flexible design‌: The thin-walled design structure is small in size and can be customized according to customer needs.
• Good quality consistency‌: High-end equipment and precision molds are used in the production process to ensure product quality.

‌Applications
JF bimetallic bearings are widely used in engineering machinery, automotive industry, textile machinery and other fields.

• Engineering machinery‌: Used for the track roller sleeves and towing wheel sleeves of the chassis walking mechanism, bearing heavy loads and ensuring stable operation of the machinery‌.
• Automotive industry‌: Applied to key parts such as balance shaft bushings, steel plate pin bushings, and steering knuckle main pin bushings to improve the overall performance and reliability of the car.
• Other industrial fields‌: Such as gear pump side plates, plunger pump side plates, internal combustion engine main bearings, thrust washers, etc., to meet the use requirements under various complex working conditions.

In addition, JF bimetallic bearings are also particularly suitable for medium speed and medium load and low speed and high load occasions. Various oil grooves and oil holes can be processed according to the use conditions to adapt to different lubrication conditions. For example, in low-speed occasions, grease can be added during assembly and fully enclosed, medium-speed occasions are equipped with oil cups for thin oil lubrication, and high-speed occasions are immersed in oil for use.
