What is PTFE lined bearing strip?
PTFE lined bearing strip is a composite self-lubricating bearing material used to manufacture custom bearing components. Bowman's WMU® bearing strip consists of a carbon steel backing, a porous sintered bronze layer, and a low-friction PTFE sliding surface, providing excellent wear resistance, low friction, and maintenance-free performance for a wide range of industrial applications.
What sizes of WMU® bearing strip are available?
Bowman supplies WMU® bearing strip in a range of metric and imperial sizes from stock to suit various engineering requirements. Bronze-backed versions are also available to order. If you need assistance selecting the correct dimensions, Bowman's technical team can recommend the most suitable option for your application.
Can I cut WMU® bearing strip to a custom size?
Yes. WMU® bearing strip can be cut, formed, and machined into bespoke components to meet specific design requirements. Bowman also offers an in-house machining service to manufacture custom-sized bushings, thrust washers, wear plates, guide strips, and other bearing components from the material.
How do I use bearing strip to make a bushing?
Bearing strip is cut to the required dimensions, formed into a cylindrical shape, and installed into a housing to create a custom bushing. This approach allows engineers to manufacture non-standard bearing sizes where off-the-shelf products are unavailable, making WMU® bearing strip ideal for OEM production, repairs, and replacement components.
What temperatures can WMU® bearing strip handle?
WMU® PTFE lined bearing strip is designed to operate across a wide temperature range typical of PTFE-lined composite bearing materials. The exact operating temperature depends on the application, load, speed, and operating environment. Bowman can provide detailed temperature limits and technical guidance to ensure the material is suitable for your specific application.
