Frequently Asked Questions
What is a WMB bronze wrapped bearing?
A WMB bronze wrapped bearing is a plain bearing developed for slow-speed, high-load applications, particularly where oscillating motion is involved. The WMB range is available with lubrication pockets, through-holes, and grooves.
What loads can these bearings handle?
WMB bronze wrapped bearings are designed for high-load applications. The load capacity depends on the bearing size, operating conditions, and application. Contact Bowman to discuss your specific requirements.
How is wrapped different from solid bronze?
WMB bearings are a wrapped bronze bearing solution designed for slow-speed, high-load applications. The choice between a wrapped bearing and a solid bronze bearing depends on the application, load, movement, and operating conditions.
What sizes are available?
The WMB range is available in metric sizes only. Bowman’s in-house machining service can also produce non-standard sizes to suit specific customer requirements.
How do I request a quote?
