What is a WMG plastic plain bearing?

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

What is the difference between WMG plain bearings and bronze plain bearings?

WMG plain bearings are thermoplastic and offer advantages such as low friction, high abrasion resistance, and resistance to corrosion. Bronze plain bearings can provide higher load capacity in certain applications and are often selected for demanding mechanical loads. The right choice depends on the application's load, speed, environment, and lubrication requirements.

What sizes of WMG plain bearings are available?

WMG plain bearings are available in metric sizes only. As a specialist WMG plastic plain bearings manufacturer, Bowman can also produce non-standard dimensions through its in-house machining service.

In what industries are WMG plain bearings used?

WMG bearings can be used across industries where low friction, abrasion resistance, and reliable performance in dusty or challenging environments are required. They can be suitable for industrial machinery, material handling equipment, automation, and other applications requiring a dust resistant plain bearing or corrosion resistant plain bushing.

Can Bowman make custom WMG plain bearing sizes?

Yes. Bowman’s in-house machining service can produce non-standard WMG sizes to meet customer-specific requirements. This allows us to provide customised thermoplastic plain bushing, low friction plastic bearing, and thermoplastic sleeve bushing UK solutions.
