WMX® Washers

WMX® Washers from Bowman

WMX® Washers from Bowman

Bowman WMX® acetal lined thrust washers are engineered to provide reliable axial load support in applications involving rotary, oscillating, and intermittent movement. Designed for wet-running and grease-lubricated environments, these POM thrust washers combine excellent wear resistance with low friction to deliver dependable, long-lasting performance. Each washer is manufactured using a durable carbon steel backing, a porous sintered bronze intermediate layer, and an acetal co-polymer layer, creating a robust composite bearing solution capable of withstanding demanding operating conditions while maintaining smooth, efficient motion.

The acetal sliding surface offers excellent dimensional stability, good impact resistance, and outstanding performance under lubricated conditions. Unlike PTFE-lined products intended for dry-running applications, WMX® washers are optimised for environments where lubrication is available, making them ideal wet running thrust washers for machinery subjected to continuous rotation or oscillating movement. Their composite construction distributes axial loads efficiently while reducing wear on mating components, helping extend equipment life and minimise maintenance requirements.

As an experienced acetal washer manufacturer, Bowman supplies WMX® washers in a wide range of standard metric and imperial sizes to support OEM production, maintenance, and replacement requirements. Where standard dimensions are unsuitable, our in-house machining service can manufacture bespoke washers to meet exact customer specifications. Custom internal diameters, external diameters, thicknesses, and tolerances can all be produced, providing engineers with flexible solutions for specialised applications.

These polymer lined thrust washers are widely used across hydraulic systems, construction equipment, agricultural machinery, pumps, gearboxes, industrial automation, material handling equipment, and general engineering applications. The carbon steel backed acetal washers provide the strength required for demanding operating conditions while the polymer lining ensures smooth movement under lubrication. As a trusted thrust washer supplier UK, Bowman combines precision manufacturing, extensive stock availability, and technical expertise to deliver high-quality bearing solutions that maximise equipment reliability, reduce wear, and support long service life across a broad range of industrial sectors.

What is an acetal lined thrust washer?

An acetal lined thrust washer is a composite bearing component designed to support axial loads while providing low-friction movement in lubricated applications. Bowman WMX® washers feature a carbon steel backing, a porous sintered bronze interlayer, and an acetal co-polymer sliding surface, offering excellent wear resistance, durability, and reliable performance in rotary and oscillating applications.

When should I use acetal instead of PTFE for a thrust washer?

Acetal-lined thrust washers are best suited to wet-running or grease-lubricated applications involving higher loads and rotary or oscillating motion. PTFE-lined washers are generally preferred for dry-running applications with little or no lubrication. The choice depends on the operating environment, load, speed, and lubrication conditions.

Can WMX® washers run in wet or lubricated conditions?

Yes. WMX® POM thrust washers are specifically designed for wet-running and lubricated environments. Their acetal co-polymer sliding surface delivers low friction, excellent wear resistance, and long service life when operating with grease or other suitable lubricants.

What sizes of WMX® washers are available?

Bowman supplies WMX® washers in a comprehensive range of standard metric and imperial sizes to suit a wide variety of industrial applications. Standard stock sizes enable fast delivery, while technical support is available to help select the correct washer for your application.

Can I order custom WMX® washer sizes?

Yes. Bowman offers an in-house machining service to manufacture WMX® washers in bespoke dimensions. Custom internal diameters, external diameters, thicknesses, and other specifications can be produced to meet the requirements of OEMs, replacement parts, and specialised engineering applications.
