The bushing and sleeve is used for the outside of the mechanical parts, in order to achieve the sealing, wear protection and other functions of the match, refers to the role of the liner ring.

In the moving parts, wear of the parts is caused by long-term friction. When the gap between the shaft and the holes wears to a certain degree, the parts must be replaced. We choose the material with low hardness and good abrasion resistance as the sleeve or liner. The sleeve, which can reduce the wear of the shaft and the seat, can be replaced when the sleeve or bush wears to a certain degree, so that the cost for replacing the shaft or the seat can be saved.

The function of bushings

The flexibility of the bushing is relatively high, and it has many functions. In general, the bushing is a type of component that protects the equipment. The use of bushings can reduce equipment wear, vibration and noise, and have anti-corrosion effects. The use of bushings also facilitates the maintenance of mechanical equipment and simplifies the structure and manufacturing process of the equipment.

Bushing Features 

Small deformation, high precision; good concentricity; good verticality; high wear resistance.

Application of Cold Forging Bushing Sleeves

Used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various types of machine tools and interchangeable mechanical drive linkage. For example: pulleys, sprockets, gears, propellers, large fans, and other types of couplings, etc.; Features: Large torque, high accuracy, quick and easy assembly and disassembly, easy operation, good positioning, reduced scrapping rate of the shaft and hub being engaged, Reusable, no damage to the mating surface, is the best and most economical choice.
