Products Details

Bushing is a supporting part used outside the mechanical parts to achieve the functions of sealing and wear protection. It refers to the ring sleeve acting as a gasket. In the moving parts, the parts are worn due to long-term friction. When the clearance between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer selects the materials with low hardness and good wear resistance as the shaft sleeve or bushing in the design, which can reduce the wear of the shaft and seat. When the shaft sleeve or bushing is worn to a certain extent, it can be replaced, In this way, the cost of replacing the shaft or seat can be saved. Generally speaking, the bushing adopts interference fit with the seat and clearance fit with the shaft, because wear can not be avoided anyway, which can only prolong the service life, and the shaft parts are relatively easy to process.
