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.
