1. Save a large amount of copper materials and save labor hours for making copper sleeves for vehicles
2. Compared with car made shaft sleeves and rolling bearings, it is lighter in weight and lower in cost；
3. It can process various cavities, pits, and store a certain amount of grease on the friction surface, extending the refueling time by 5 times compared to copper sleeves；
4. Extremely high load-bearing capacity, especially suitable for rough friction surfaces；
Products available: straight sleeve, thrust washer, flanged sleeve, bearing shell, sliding plate, steel sleeve assembly.
