Frequently Asked Questions
What is WMU PTFE strip used for?
WMU PTFE strip is a self-lubricated bearing material made from carbon steel with a sintered bronze layer filled with PTFE. It is used for industrial bearing and sliding applications where a PTFE-lined strip material is required.
What thicknesses are available?
WMU PTFE bearing strip is available in metric and imperial sizes from stock. The available thickness depends on the specific strip size and specification. Contact Bowman for details on the available options.
Can the strip be custom cut?
Yes. Bowman’s in-house machining service can produce non-standard sizes to suit specific customer requirements. This makes WMU bearings suitable for applications requiring dimensions beyond the standard range.
What are the load limits?
Load limits depend on the bearing dimensions, operating conditions, and specific application. For the appropriate WMU PTFE bearing specification for your application, contact Bowman for technical guidance.
How do I request a quote?
To request a quote, provide your required dimensions, quantity, and application details.
