Common Industry Challenges We Address

In automotive suspension systems, conventional bushings often face premature wear due to high-frequency oscillation, inadequate lubrication, and exposure to extreme temperatures. These issues lead to increased maintenance downtime, unexpected component replacement costs, and compromised vehicle handling performance. Our DU self-lubricating bushing is engineered to directly resolve these critical operational concerns.

Key benefits engineered for your application:

Self-lubricating PTFE layer eliminates the need for external grease maintenance, reducing long-term service costs
Exceptional load capacity (up to 250N/mm² static) ensures reliable performance under continuous heavy-duty operation
Wide operating temperature range (-195°C to +280°C) maintains structural integrity in extreme environments
Low friction coefficient (0.04-0.20) minimizes energy loss and heat generation during oscillation
Multiple material backing options available to match your specific corrosion resistance requirements
Competitive Advantage
Rich experience for producing different kinds of bushes
Plenty machine can offer production capacity
Strict quality control plan for the whole production line
Testing for every step to assure the quality
Clean and tidy workshop
Applications

Printing presses, textile machines, hydraulic carrier, tobacco machine, medical machinery, micro-motor, automobiles and motorcycles

Packaging & Delivery

Packaging Detail: Dry bearing bushing Standard package or according to your requirements

Standard package:

Double layers plastic bag package
Thin cartons
Then in big wooden case.

Delivery Detail: 10-25 days

Frequently Asked Questions Q: What is the difference between DU bushing and traditional bronze bushings?

DU bushings feature a three-layer composite structure with a PTFE-based self-lubricating inner layer, which eliminates the need for regular grease lubrication. Traditional bronze bushings require continuous external lubrication and typically have higher friction coefficients, leading to more frequent maintenance and shorter service intervals.

Q: Can DU bushings operate in dry running conditions?

Yes, DU bushings are specifically designed for dry running applications. The PTFE inner layer provides excellent self-lubricating properties with a friction coefficient as low as 0.04, enabling reliable operation without external lubrication at speeds up to 2.5m/s under dry friction conditions.

Q: What is the minimum order quantity and typical lead time?

The minimum order quantity is 500 pieces. Typical delivery time is 10-25 days depending on order specifications and quantity. Custom dimensions are available upon request with engineering drawing review.

Q: Are ROHS-compliant (lead-free) versions available?

Yes, all material backing types (steel, bronze, stainless steel) are available in lead-free variants that comply with ROHS environmental standards. Please specify your compliance requirements when placing an order.

Q: What certifications does this product hold?

This product is manufactured under IATF 16949:2016 certified quality management system, ensuring automotive-grade production standards, full material traceability, and consistent quality across all production batches.
