1. The bearing sleeve is widely used in applications with light loads and ease of disassembly. Many bearings encounter difficulties during assembly and disassembly, particularly when assembling internal bearings within enclosures, where conditions impose limitations. The use of bearing sleeves can resolve a significant challenge in assembly and disassembly.

2. The bearing sleeve can be adjusted for tightness, which relaxes the machining precision of many boxes, further enhancing the efficiency of box machining.

3. The installation of bearing bushes also resolves the axial movement of the bearings. Therefore, bearing bushes are widely used, yet they also have certain shortcomings; the precision of the bearing bushes directly affects the radial跳动 of the shaft.

4. The critical role of bushings in machinery is to provide stability. When the gear shaft is in motion, it is essential to prevent it from undergoing directional displacement due to vibration, which is where copper bushings come into play to assist in the stabilization.
