Seamless steel tubes of appropriate specifications and materials are selected according to the requirements of the bushings.

In order to improve the mechanical properties of the bushing, such as hardness, strength, and wear resistance, heat treatment processes such as quenching and tempering are often carried out. Heat treatment can optimize the microstructure of the steel, making the bushing better able to withstand the working conditions.

Surface treatment is performed on the bushing to further improve its performance. Common surface treatment methods include electroplating, coating.These treatments can improve the corrosion resistance, wear resistance, and lubricity of the bushing surface, prolonging its service life.
