What are WMX® acetal plain bearings made of?
WMX® acetal lined bearings are manufactured as steel backed acetal bearings, combining a durable steel backing with a high-performance acetal copolymer lining. This construction provides excellent strength, low friction, and outstanding wear resistance. These acetal copolymer plain bearings are designed to deliver reliable performance in demanding industrial environments with extended re-lubrication intervals.
What is the maximum load capacity of WMX® Bearings?
WMX® Bearings are engineered to support high radial loads and perform reliably in demanding operating conditions. Their acetal lined wrapped bearings construction provides excellent load-carrying capability while maintaining dimensional stability and wear resistance. The exact load capacity depends on factors such as bearing size, shaft material, lubrication, operating speed, and application conditions. Bowman's engineering team can recommend the appropriate bearing for your specific requirements.
What applications are WMX® Bearings suitable for?
WMX® acetal lined bearings are ideal for acetal bearings rotary oscillating applications where high loads, low friction, and long service life are required. They are widely used in automotive systems, agricultural machinery, construction equipment, hydraulic cylinders, material handling equipment, machine-building, and industrial engineering applications. As low wear acetal bearings, they are particularly suitable where extended lubrication intervals are desirable.
Are there custom sizes available for WMX® Bearings?
Yes. Bowman offers wrapped acetal bearings in a comprehensive range of standard metric and imperial sizes, along with bespoke manufacturing for specialist applications. Custom dimensions, configurations, and application-specific solutions are available to ensure the bearing meets your exact performance and installation requirements.
How do WMX® Bearings reduce wear and friction?
WMX® acetal lined bearings reduce wear and friction through their advanced acetal copolymer bearing surface, which provides excellent sliding characteristics and low friction under lubricated operating conditions. The combination of a durable steel backing and premium polymer lining creates low wear acetal bearings that distribute loads efficiently, minimize surface wear, and extend equipment service life, making them an excellent choice for demanding rotary and oscillating applications.
