    WMUB® Plain Bearings from Bowman

    WMUB® Plain Bearings from Bowman

    The WMUB® Plain Bearing range builds on Bowman’s proven WMU wrapped bearing technology by incorporating a bronze backing for greater strength, durability, and performance in demanding industrial environments. Manufactured with a solid bronze backing, a porous sintered bronze interlayer, and a low-friction PTFE sliding surface, these bronze backed plain bearings deliver excellent wear resistance, reduced friction, and long service life without the need for continuous lubrication. The combination of advanced composite materials and robust construction makes them ideal for applications where reliability, efficiency, and minimal maintenance are essential.

    A major advantage of the WMUB® range is its enhanced load-carrying capability. Compared with steel-backed alternatives, the bronze backing provides greater compressive strength, improved fatigue resistance, and superior structural rigidity under heavy loads. This allows the bearings to maintain dimensional stability and consistent performance in applications subjected to continuous operation, shock loading, or frequent start-stop cycles. As a high load PTFE bushing, the WMUB® range is particularly well suited to demanding engineering environments where durability is critical. The bronze construction also offers excellent corrosion resistance, making these corrosion resistant bushings suitable for marine, offshore, chemical processing, and other harsh operating conditions.

    The PTFE sliding layer provides exceptionally low friction and excellent dry-running characteristics, allowing these dry running bronze bushings to operate with little or no lubrication. Reduced maintenance requirements help minimise downtime while preventing contamination in applications where grease cannot be used. This combination of low wear and reliable performance extends equipment service life and lowers overall operating costs.

    Bowman supplies metric bronze bushings and imperial sizes as standard, with an in-house machining service available to manufacture bespoke dimensions for OEM and replacement applications. As an experienced PTFE bearing manufacturer UK, Bowman also produces custom bronze backed PTFE bushing solutions to suit unique engineering requirements. Widely used as heavy duty plain bearings in hydraulic equipment, construction machinery, mining, marine systems, pumps, industrial automation, and material handling equipment, WMUB® bearings deliver dependable, maintenance-free performance where high loads, low friction, and long service life are essential.

    Frequently Asked Questions

    What are WMUB® bronze backed plain bearings?

    WMUB® bronze backed plain bearings are self-lubricating composite bearings designed for demanding applications requiring higher load capacity and long service life. They feature a solid bronze backing, a porous sintered bronze interlayer, and a low-friction PTFE sliding surface, delivering excellent wear resistance, reduced friction, and maintenance-free operation.

    How does WMUB® compare to WMU® for high load applications?

    While both WMU® and WMUB® bearings use a PTFE-lined sliding surface, WMUB® bearings incorporate a bronze backing instead of steel. This provides greater compressive strength, improved fatigue resistance, and enhanced structural rigidity, making WMUB® the preferred choice for high load PTFE bushings and more demanding operating conditions.

    Can WMUB® plain bearings run without lubrication?

    Yes. WMUB® plain bearings are specifically designed for dry-running operation. The PTFE sliding layer provides excellent low-friction performance without the need for continuous lubrication, reducing maintenance requirements while delivering reliable long-term performance.

    What is the PV rating of WMUB® bronze backed bearings?

    WMUB® bearings are engineered to provide excellent PV (pressure-velocity) performance for demanding industrial applications. The maximum allowable PV value depends on operating conditions such as load, speed, shaft material, temperature, and duty cycle. Bowman can provide detailed technical guidance and performance data to help select the correct bearing for your application.

    Where are bronze backed plain bearings typically used?

    Bronze backed plain bearings are commonly used in heavy-duty applications where high loads, corrosion resistance, and maintenance-free operation are essential. Typical industries include construction, mining, marine, agriculture, hydraulic equipment, industrial automation, material handling, pumps, compressors, and general engineering, where long service life and dependable performance are critical.
