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

FAQs

1. What is a WMU washer used for?

WMU washers are used for axial (thrust) load support while reducing friction in rotating or sliding assemblies.

2. Do WMU washers require lubrication?

No. They are self-lubricating due to the PTFE layer.

3. Are 32mm and 70mm washers suitable for industrial use?

Yes. Both sizes are commonly used in industrial machinery and mechanical systems.

4. Can WMU washers be used in dry environments?

Yes. They are designed to perform reliably without external lubrication.
