What is a bronze wrapped thrust washer?

A bronze wrapped thrust washer is a flat bearing component manufactured from premium CuSn8 phosphor bronze alloy and designed to support axial loads while reducing friction between rotating or stationary surfaces. These CuSn8 thrust washers offer excellent wear resistance, high load capacity, and effective lubricant retention, making them ideal for demanding industrial applications operating at low speeds and under heavy loads.

When should I use solid bronze instead of a lined thrust washer?

Choose solid bronze thrust washers when your application involves high axial loads, slow speeds, oscillating motion, or shock loading and grease or oil lubrication is available. Compared with PTFE- or acetal-lined thrust washers, WMB® solid bronze washers provide greater structural strength, higher load capacity, and superior durability in harsh operating environments such as construction, mining, agriculture, and heavy industrial machinery.

What sizes of WMB® washers are available?

Bowman's WMB® bronze wrapped washers are available in a comprehensive range of standard metric sizes to suit a wide variety of industrial applications. For projects requiring non-standard dimensions, our in-house machining service can manufacture custom washers to meet your exact size and application requirements.

Can I order custom WMB® washer sizes?

Yes. As an experienced solid bronze washer manufacturer, Bowman offers bespoke machining services to produce custom wrapped bronze thrust washers in a wide range of diameters, thicknesses, and configurations. Our engineering team can manufacture washers tailored to your equipment and operating conditions.

Where are bronze thrust washers typically used?

High load bronze washers are widely used in construction equipment, mining and quarrying machinery, agricultural implements, automotive systems, marine equipment, hydraulic machinery, and material handling systems. They are particularly suitable for oscillating motion thrust washer applications where high axial loads, repeated movement, and reliable long-term performance are required.
