WMU® Plain Bearings

WMU® Plain Bearings from Bowman

WMU® Plain Bearings from Bowman

Bowman WMU® PTFE lined plain bearings are engineered to deliver dependable, maintenance-free performance in demanding applications where low friction, high wear resistance, and long service life are essential. Manufactured using a robust carbon steel backing, a porous sintered bronze intermediate layer, and a PTFE-based sliding surface, these steel backed PTFE bearings combine excellent load-carrying capability with outstanding dry-running performance. The composite construction eliminates the need for continuous lubrication, making the bearings ideal for environments where regular maintenance is difficult or grease contamination must be avoided.

Designed for reliability under a wide range of operating conditions, WMU® bearings offer excellent PV (pressure-velocity) performance, enabling them to withstand demanding combinations of load and sliding speed while maintaining low friction and minimal wear. Their PTFE lining provides smooth operation during start-up and continuous movement, while the sintered bronze layer securely bonds the sliding surface to the steel backing for enhanced durability. The bearings also operate across a broad temperature range typical of PTFE-lined composite bearing materials, making them suitable for applications exposed to both elevated and sub-zero temperatures. Bowman’s technical team can advise on recommended operating limits based on specific load, speed, and environmental conditions.

As an experienced PTFE bushing manufacturer, Bowman supplies metric PTFE plain bearings and imperial PTFE bushings UK from stock, ensuring fast delivery for maintenance, OEM production, and replacement requirements. For applications that require bespoke dimensions, our in-house machining service can manufacture non-standard sizes to precise customer specifications, helping engineers achieve the perfect fit without compromising performance.

These maintenance free plain bearings are widely used across hydraulic equipment, construction machinery, agricultural equipment, pumps, compressors, industrial automation systems, material handling equipment, marine applications, and general engineering. Their ability to perform as dry running plain bushings significantly reduces maintenance costs while extending equipment service life. The combination of low friction, excellent wear resistance, and dependable operation makes WMU® bearings an ideal choice for engineers seeking durable low friction plain bushings that deliver consistent performance in challenging industrial environments.

What is a PTFE lined plain bearing?

A PTFE lined plain bearing is a self-lubricating bearing designed to provide low-friction, maintenance-free operation. Bowman WMU® plain bearings feature a carbon steel backing, a porous sintered bronze interlayer, and a PTFE-based sliding surface, delivering excellent wear resistance, high load capacity, and long service life across a wide range of industrial applications.

Can WMU® plain bearings run without lubrication?

Yes. WMU® PTFE lined plain bearings are specifically designed for dry-running operation. The PTFE sliding layer provides excellent low-friction performance without the need for continuous lubrication, making these maintenance free plain bearings ideal for applications where regular greasing is impractical or contamination must be avoided.

What is the PV rating of WMU® PTFE lined bearings?

WMU® bearings are designed to offer excellent PV (pressure-velocity) capability, allowing them to perform under demanding combinations of load and sliding speed. The maximum permissible PV value depends on factors such as operating temperature, shaft material, lubrication conditions, and duty cycle. Bowman can provide detailed technical data and application-specific recommendations to ensure optimum bearing performance.

What sizes of WMU® plain bearings are in stock?

Bowman stocks a comprehensive range of metric PTFE plain bearings and imperial PTFE bushings UK to suit a wide variety of industrial applications. In addition to standard sizes, Bowman offers an in-house machining service to manufacture non-standard bearings to meet specific customer requirements.

How do WMU® bearings compare to bronze bushings?

Compared with traditional bronze bushings, WMU® PTFE lined plain bearings provide significantly lower friction, require little or no lubrication, and offer improved wear resistance in many applications. Their self-lubricating composite construction helps reduce maintenance requirements, minimise downtime, and deliver more consistent performance, particularly in dry-running or difficult-to-access operating environments.
