Engineering Advantages

1 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.

Critical Design Considerations

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:

Multi-layer construction with PTFE/lead initial transfer film (0.01-0.03mm) ensures immediate lubrication upon first movement, preventing dry-start scoring

Sintered bronze powder interlayer (0.20-0.35mm) acts as both a lubricant reservoir and thermal conductor, efficiently dissipating friction heat away from the contact surface

Low carbon steel backing provides exceptional structural integrity with static load capacity up to 250N/mm² for heavy-duty impact resistance

Wide dimensional range from 6mm ID to 300mm ID with flange diameters up to 340mm covers most suspension component applications

Copper/tin plating (0.002mm) delivers reliable corrosion protection for long service life in harsh under-vehicle environments

Competitive Advantage

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

Applications

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

Packaging & Delivery

Packaging Detail: Products packed by plastic bag, each bag contain 500pcs or 5kg Max, packed Cartons max 20kgs each. Delivered by Wooden package or Iron cage / Pallet as requested, Standard Size 800x800x1200; Max G.W. 800kgs

Frequently Asked Questions

Q: What makes the DU bushing impact-resistant for suspension applications?

The 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.

Q: What size range is available for flange DU bushings?

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.

Q: Can these bushings be used in food-grade or pharmaceutical applications?

Yes, we offer lead-free bearing variants specifically designed for food machinery and pharmaceutical equipment.

Q: What is the difference between dry running and hydrodynamic operation?

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.

Q: How is product quality verified before shipment?

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.
