Engineered for heavy-duty automotive suspension systems, the XIAYI SF-1D DU bushing delivers dependable impact resistance and extended service life under demanding operating conditions. Built on a steel backing with a sintered bronze interlayer and a PTFE anti-wear sliding surface, this oilless bearing combines low friction with high load capacity, helping manufacturers and aftermarket suppliers reduce downtime and lower total cost of ownership.
Why Buyers Choose the SF-1D DU Bushing
| Common Challenge | XIAYI Solution |
|---|---|
| Premature bushing wear caused by shock and vibration | Sintered bronze interlayer plus PTFE sliding surface absorbs impact and keeps dimensions stable over long duty cycles |
| Frequent relubrication and costly maintenance downtime | Self-lubricating design runs oilless or with minimal grease, cutting service intervals and labor cost |
| Clearance growth that causes rattling and loose steering feel | Low friction coefficient and anti-wear surface keep clearance tight for precise, confident handling |
| Corrosion in wet or road-salt environments | Tin or copper plated steel backing resists corrosion and extends component life |

Material Construction
1. PTFE with mixture 0.01~0.03mm
2. Porous bronze 0.2~0.3mm
3. Steel backing 0.7~2.3mm
4. Tin-plating 0.005mm or copper plating 0.008mm
Key Performance Features
1. No pre-lubrication required
2. Able to work under extreme high and low temperature with low speed
3. Working temperature range: -195°C ~ +280°C
4. Non-oil or less lubrication with low maintenance and better abrasion resistance
5. Low friction index and strong anti-aging performance
6. Resists abrasion with a low coefficient of friction for long operation life
7. Thin-walled and light in weight, allowing the machine to be built more compact
8. Forms a transfer film during operation for safe, trouble-free running
9. Low demand on mating surface shape, lowering the cost of mating components
10. No water or oil absorption, small thermal expansion and good thermal conductivity with stable dimensions

Frequently Asked Questions
Q: What makes this DU bushing impact resistant?
A: The combination of a steel backing, a sintered bronze interlayer and a PTFE anti-wear surface lets the SF-1D absorb shock loads while keeping friction low and dimensions stable.
Q: Can it run without lubrication?
A: Yes. It is a self-lubricating, oilless bearing. It can operate with no pre-lubrication, or with minimal lubrication if preferred.
Q: What temperature range does it support?
A: It operates reliably from -195°C to +280°C, making it suitable for both cold-start and high-temperature applications.
Q: What materials is the SF-1D made of?
A: PTFE sliding layer (0.01~0.03mm), porous bronze interlayer (0.2~0.3mm), steel backing (0.7~2.3mm), and tin or copper plating.
Q: Do you offer customized sizes?
A: Yes. We offer a full range of standard sizes as well as custom dimensions to match your drawings.
