Engineering Advantages1 PTFE / Pb mixture 0.01-0.03mm, provides an excellent initial transfer film
2 sintered bronze powder 0.20-0.35mm, provides Max thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE- lead mixture.
3 Low carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4 copper / Tin plating 0.002mm, provides good corrosion resistance.

Automotive suspension engineers often encounter difficulties with bushing degradation under high-frequency impact loading, thermal breakdown at elevated operating temperatures, and premature wear in dry-start conditions. The Impact Resistant DU Bushing is purpose-built to overcome these challenges:
1. A complete set of testing equipment |
2. Rich experience in bushing production |
3. Good outsource factory |
4. Have an audit for material supplier every year |
Stainless steel bushing is widely used in strong acid and alkali situation, such as chemical industry, pumps and valves.
Lead free bearing is widely used in food machine, pharmaceutical machine

Frequently Asked QuestionsThe three-layer composite design combines a low carbon steel backing for structural strength, a sintered bronze powder interlayer for thermal management, and a PTFE/lead transfer film for friction reduction.
Our flange DU bushings are available from 6mm minimum ID up to 300mm maximum ID, with outer diameters ranging from 8mm to 320mm, and flange diameters from 12mm to 340mm. Maximum length capacity is 130mm.
Yes, we offer lead-free bearing variants specifically designed for food machinery and pharmaceutical equipment.
In dry running conditions, maximum speed is 2m/s with a continuous PV limit of 1.8N/mm²·m/s. Under hydrodynamic (oil-lubricated) operation, speeds exceed 2m/s with significantly higher PV limits.
We maintain a complete set of testing equipment for dimensional verification, material certification, and performance validation. Annual supplier audits and IATF 16949:2016 certified processes ensure consistent quality.
