BOWMAN'S WMU® PTFE LINED BEARINGS: HIGH‑PERFORMANCE, DRY‑RUNNING APPLICATIONS
Bowman’s WMU PTFE lined bearings are engineered to deliver exceptional performance in demanding dry running PTFE bearings applications where low friction, minimal wear, and maintenance-free operation are essential. Featuring a robust steel backing with a premium PTFE sliding layer, these low friction PTFE bushings create a protective transfer film on the mating surface, reducing friction and extending the service life of both the bearing and the shaft without requiring external lubrication.
As a trusted PTFE lined wrapped bearing manufacturer, Bowman offers a comprehensive range of standard metric and imperial sizes alongside fully customized PTFE lined bearing solutions to meet specific application requirements. Our WMU® bearings are widely used in automotive, hydraulics, construction equipment, agricultural machinery, and precision engineering, including PTFE bushings for hydraulics and automotive suspension PTFE bearings where consistent, low-friction performance is critical.
Alongside our standard steel backed PTFE bearings for customers across the USA and worldwide, Bowman also manufactures the WMU-B and WMU-SS ranges featuring bronze or stainless-steel backing strips for applications requiring enhanced corrosion resistance or specialised material compatibility.
