PTFE Wrapped Bearings & PTFE Lined Bushes – High‑Load, Dry‑Running Performance
Split WMU Bearings – High‑Performance PTFE‑Lined Wrapped Bearings for Demanding Industrial Applications.
Split WMU bearings deliver exceptional low‑friction performance, high load capacity, and long service life — making them the ideal choice for engineers seeking a reliable, maintenance‑friendly bearing solution. Manufactured using a PTFE‑lined wrapped structure with a steel or bronze backing, these bearings are designed for dry‑running, high‑duty, and repetitive‑motion environments.
Split WMU bearings (also known as PTFE‑lined wrapped bearings) are engineered plain bearings constructed from:
- Lead‑free PTFE polymer fibre lining – forms a self‑lubricating transfer film on the mating surface
- Sintered bronze powder layer – improves thermal conductivity and stores PTFE lubricant
- Steel backing (or bronze/stainless variants) – provides high load capacity and excellent heat dissipation
- Copper/tin plating – enhances corrosion resistance
These features combine to create a bearing that is durable, versatile, and ideal for dry or boundary‑lubricated applications.
- Ultra‑Low Friction - PTFE lining forms a protective transfer film, reducing wear and extending component life.
- High Load Capacity - Steel‑backed construction ensures stability under heavy dynamic and static loads.
- Excellent Thermal Performance - Bronze powder layer dissipates heat efficiently, making WMU bearings suitable for high‑duty cycles.
- Corrosion Resistant - Copper/tin plating protects against moisture, chemicals, and environmental exposure.
- Maintenance‑Free Operation.
Ideal for applications where lubrication is difficult or impossible.
