All-in-one service provider from raw materials to finished products

The 5620 series bimetal bushings, bushes, thrust pads are made of high-quality low-carbon steel as the base body, and the surface is sintered with bronze powder, which is suitable for rotation and swinging motion under high load and low speed. It has the characteristics of low friction coefficient, good wear resistance, long service life, good anti-seizure performance, etc. The copper alloy layer can be processed into various types of oil holes and oil grooves according to requirements. Products are widely used in mining machinery, steam locomotives, construction machinery, agricultural machinery, steel rolling machinery, etc.

The 5621 solid lubricating bearing is a new type of sliding bearing made of 5620 bimetallic material as the matrix and embedded with a special solid lubricant. Due to the high-strength bearing alloy material as the matrix, and the carefully selected polymer filler material as the wear-resistant agent, the lubricating surface with a reasonable spiral angle diamond block uniform distribution, the lubricating area reaches 25%, so it can play an outstanding low Friction, good lubricity and abrasion resistance eliminates oiling. The product has been widely used in industries such as lifting, micro-motors, elevators, cranes and metallurgical machinery.

5622 Bimetal Bearing 5622 bimetallic bearing is made of steel plate as the base and sintered CuPb24Sn4 material on the surface. The product has good fatigue strength and load-bearing capacity. It is suitable for medium speed, medium load, and oil lubricated occasions. When the surface is plated with soft alloy, it can be used as high-speed internal combustion engine bearings and connecting rod bushings to achieve good wear resistance and fatigue resistance.

The 5120 series bronze rolled bearing sleeve is a new-generation sleeve developed and designed by our company on the basis of steel-copper-lead bimetal sleeve products. This product is very common in foreign countries. With the increasing number of new types of machinery and equipment introduced in China, designers are increasingly demanding new materials and bushings. Therefore, this product has a wide range of applications in our machinery manufacturing. And practical value. The biggest feature of 5120 series bushings is the thin-walled structure, which does not occupy a lot of assembly space. The shaft sleeve material adopts specially formulated high-density copper alloy strip. Compared with the traditional paved copper sleeve, it has the advantages of high density, no air shrinkage cavity, large carrying capacity, and wear resistance and fatigue resistance. Shaft sleeve manufacturing adopts advanced tooling molds, which can process oil pockets, oil pits and oil grooves suitable for various engineering conditions on the friction surface of the strip, so that the sleeve can store a large amount of lubricating grease when used, extend the interval between refueling, effective Increased the service life.
5120 series bearings are widely used in agricultural machinery, construction machinery, construction machinery, automobile industry, etc.

5131 series bronze rolled bearings are the same as 5120Material. Our unit has developed a new generation of product sleeves based on similar foreign products. It can improve product design and replace the original copper sleeves, which can reduce procurement costs. Therefore, the products are manufactured in our machinery. There are a wide range of practical values and application areas.

The shaft sleeve material adopts specially formulated high-density copper alloy strip. Compared with the traditional paving copper sleeve, it can process oil holes, oil pits and oil grooves suitable for various engineering conditions on the friction surface of the strip, and arrange lubrication through holes, so that the sleeve can store a large amount of lubrication when in use Oilfat, prolong the interval between adding oil, effectively increase the service life.
5131 series bearings are widely used in agricultural machinery, construction machinery, construction machinery, high load and low speed occasions.

It has the same production process and application occasions as 5120. Its base is a bronze substrate, and its diamond-shaped oil cavity is filled with graphite-based solid lubricants, so that the product can have a lower Coefficient of in the initial application stage and process. Friction, in a short period of time to break the oil can maintain a good working condition. Therefore, it is widely used in high-load and medium-speed parts such as construction machinery, gearbox transmission parts, steam and motorcycle clutches, and rotating parts of outdoor high-altitude equipment.

The product is based on a specially formulated brass material. The surface can be rolled with oil holes or oil grooves according to customer requirements. It has a high bearing pressure and good wear resistance. The product is used in automobiles, construction machinery, Machine tool industry, etc.
