Maintenance-Free SF-1W Wall Wrapped Lead-Free Bronze Bearing (Oilless Bearing Bush)

The SF-1W Wall Wrapped Lead-Free Bronze Bearing is a high-performance, self-lubricating bearing designed for heavy-duty applications where maintenance is impractical. Made from lead-free bronze and reinforced with a PTFE composite lining, it ensures zero maintenance, long service life, and environmentally friendly operation.

100% Maintenance-Free – No lubrication needed, reducing downtime and costs.
Lead-Free & Eco-Safe – Complies with global environmental regulations (RoHS/WEEE).
High Load Capacity – Wall-wrapped design enhances structural strength.
Low Friction & Wear Resistance – PTFE-based liner ensures smooth operation.
Wide Temperature Range – Performs reliably from -40°C to +250°C.

Key Features & Benefits

1. Superior Material Composition
Base Material: High-strength lead-free bronze (CuSn8) for corrosion resistance.
Lining: PTFE + fiber + solid lubricants for ultra-low friction.
Wall-Wrapped Design: Reinforced structure prevents deformation under heavy loads.

2. Maintenance-Free Operation
Self-Lubricating: Embedded solid lubricants eliminate the need for oil/grease.
Reduced Downtime: Ideal for hard-to-reach or sealed machinery.

3. High Performance in Harsh Conditions
Shock & Vibration Resistant: Handles dynamic loads without cracking.
Chemical Resistance: Withstands water, acids, and mild alkalis.

4. Applications
Automotive suspensions & chassis
Construction machinery (excavators, cranes)
Agricultural equipment (harvesters, tractors)
Industrial gearboxes & hydraulic systems

FAQ
Q: Is this bearing suitable for food-grade applications?
A: Yes! The lead-free bronze and PTFE lining meet FDA/EC1935 standards.

Q: Can it replace traditional bronze bushings?
A: Absolutely—just ensure the same dimensions and load requirements.

Q: How does the self-lubrication work?
A: Solid lubricants embedded in the PTFE layer transfer to the shaft during motion.
