WMU Type Washers – Self-Lubricating Bearing Washers

Here at Bolton Engineering Products Ltd, we have a range of robust WMU type washers which are made to provide maximum axial load support on industrial and mechanical applications. These bearing washers are self-lubricating to provide low friction and reducing wear, with a longer service life as a result—ideally suited when maintenance access is not possible.

The most popular sizes of 32mm washers and 70mm washers are stocked to fit many shaft, and housing applications.

What Is a WMU Type Washer?

A WMU washer is a self-lubricating thrust (axial) bearing washer manufactured with:

  • A steel backing for strength
  • A sintered bronze layer
  • A PTFE sliding surface for low friction
  • This construction allows smooth axial movement without external lubrication.

Key Benefits of WMU Washers

  • Self-lubricating (PTFE lined)
  • Low friction and excellent wear resistance
  • Suitable for axial / thrust loads
  • Maintenance-free operation
  • Compact design for tight assemblies
  • Reliable performance in dry or marginally lubricated conditions

Common Applications

  • Gear assemblies & gearboxes
  • Pumps and compressors
  • Electric motors
  • Industrial machinery
  • Automotive and mechanical systems
  • Thrust and axial load locations
