Product description
Material & Process:
- Made of high-strength tin bronze or aluminum bronze alloy by casting or extrusion, featuring excellent thermal conductivity, anti-friction and wear resistance, and corrosion resistance, capable of withstanding heavy loads and impact loads.
- Round blind holes are evenly distributed on the inner and outer surfaces, with solid lubricants such as graphite or PTFE embedded via press-fitting to ensure uniform distribution of lubrication points.
- The inner and outer tapered surfaces are precision turned and ground to ensure taper and dimensional tolerances for accurate fitting with the shaft or housing bore.
- Polished surface finish improves smoothness and reduces friction resistance; some variants can be tin-plated to enhance anti-seizure and corrosion resistance.
- After graphite embedding, the surface is finished to ensure uniform contact between the inner bore and the shaft, avoiding localized wear.
Application:
This tapered bushing is mainly used in tapered fitting parts of construction machinery, injection molding machines, mining equipment, hydraulic machinery and various heavy-duty equipment. It enables oil-free or low-oil operation through embedded solid lubricants without additional lubrication. The tapered design provides self-centering function, allowing radial clearance compensation via axial preload during installation to improve fitting stability. It effectively reduces friction coefficient, wear and noise between the shaft and bushing, extending equipment service life while avoiding oil leakage and pollution issues associated with traditional oil lubrication. Suitable for harsh conditions such as high temperature, dust, humidity or where continuous oil supply is unavailable, it provides stable and reliable support for equipment.
