Wrapped standard bearings

SWB Bearings

Our range of Standard Wrapped Bearings (SWB) are steel backed and lined with sintered bronze. This range is extremely tough and versatile and available in metric and imperial sizes. SWB bearings are suitable for a wide range of general purpose and heavy duty applications and can be lubricated with either oil or grease.

Our in-house machining service can produce non-standard sizes to suit specific customer requirements.
