Frequently Asked Questions
What is a WMX acetal bearing?
A WMX acetal bearing is a wrapped plain bearing with an acetal lining, designed for rotary and oscillating movement applications. The WMX range is available in metric and imperial sizes.
When should I use WMX over WMU?
WMX acetal plain bearings are designed for rotary and oscillating movement applications, while WMU bearings use a PTFE-lined construction. The right choice depends on the specific application and operating requirements.
Are WMX bearings water resistant?
WMX bearings are designed for a range of industrial applications, but water resistance depends on the specific operating conditions and application. Contact Bowman to discuss whether WMX is suitable for your environment.
What sizes are available?
WMX bearings are available in standard metric and imperial sizes. Non-standard sizes can also be produced through our in-house machining service to meet specific customer requirements.
How do I request a quote?
