What is a WMG plastic washer?

A WMG plastic washer is a thermoplastic component designed for applications requiring low friction, high abrasion resistance, and reliable performance in environments where dust or particles are present. The WMGW plastic washer range offers almost zero stick-slip characteristics and low dynamic friction.

What sizes of WMG washers are available?

WMG washers are available in metric sizes. As a specialist WMG plastic washers manufacturer, Bowman can also produce non-standard dimensions through its in-house machining service to meet specific application requirements.

In what environments do WMG washers perform best?

WMG washers are particularly suited to environments where dust, particles, or abrasive conditions are a concern. Their high wear resistance makes them suitable as a dust resistant thrust washer or high abrasion resistance washer for demanding applications.

Can Bowman make custom WMG washer sizes?

Yes. Bowman’s in-house machining service can produce non-standard WMG washer dimensions to meet customer-specific requirements. This provides flexibility for applications requiring a thermoplastic spacer washer UK solution or other customised configurations.

What is the difference between WMG washers and metal washers?

WMG washers offer advantages such as low dynamic friction, high abrasion resistance, and excellent performance in dusty environments. Unlike conventional metal washers, thermoplastic WMG washers can provide a low friction plastic washer solution where reduced wear, corrosion resistance, and low-maintenance operation are important.
