BOWMAN'S WMUB® PTFE LINED BEARINGS: HIGH-PERFORMANCE, DRY-RUNNING APPLICATIONS
Bowman’s WMUB® bearings are high-performance bronze backed PTFE bearings engineered for dry-running applications where low friction, excellent wear resistance, and long service life are essential. Manufactured using a bronze backing wrapped bearing construction with a premium PTFE sliding layer, these PTFE lined bronze backed bushings create a protective transfer film on the mating surface, reducing friction and extending component life without the need for external lubrication.
Our bronze backed self lubricating bearings are designed to perform reliably under demanding operating conditions across industries including automotive, hydraulics, material handling, construction equipment, and precision engineering. The wrapped construction provides excellent load capacity, dimensional stability, and resistance to wear, making WMUB® bearings suitable for oscillating, reciprocating, and rotary motion applications.
As a trusted bronze backed strip bearing manufacturer, Bowman offers an extensive range of standard metric and imperial sizes, along with bespoke solutions to meet unique application requirements. For environments where carbon steel is unsuitable, we also manufacture the WMU-SS range featuring a bronze or stainless-steel backing strip, providing enhanced corrosion resistance while maintaining the same low-friction PTFE performance.
Whether you require standard components or are looking for a reliable bronze backing PTFE bushing supplier, Bowman delivers precision-engineered solutions for customers worldwide, including those seeking wrapped bronze PTFE bearings in the USA and other global markets.
