What is a SWB bronze lined bearing?

An SWB bronze lined bearing is a steel-backed bearing lined with sintered bronze. The combination provides a tough, versatile construction suitable for general-purpose and heavy-duty applications. Bowman manufactures SWB bearings in a range of sizes and configurations.

What is the difference between WMSW and WMSWI?

WMSW refers to Bowman’s metric wrapped bearing range, while WMSWI refers to the imperial range. Both use the same steel-backed, sintered bronze construction and can be lubricated with either oil or grease.

What sizes of SWB bearings are available?

SWB bearings are available in both metric and imperial sizes. The WMSW metric wrapped bearing and WMSWI imperial wrapped bearing ranges provide standard options for a wide range of applications.

Can SWB bearings be lubricated with oil or grease?

Yes. SWB bearings can be lubricated with either oil or grease, depending on the application and operating conditions. This flexibility makes them suitable as an oil and grease lubricated wrapped bearing solution across a variety of industrial applications.

Can Bowman make custom SWB bearing sizes?

Yes. As a standard wrapped bearing manufacturer, Bowman can use its in-house machining service to produce non-standard sizes to meet specific customer requirements, including applications requiring a heavy duty wrapped bronze bushing.
