Delrin Acetal (POM) Precision Plastic Balls are precision-engineered spherical components designed for applications requiring excellent dimensional stability, low friction, and high wear resistance. Manufactured from high-quality Polyoxymethylene (POM), commonly known as Acetal or Delrin, these balls provide a durable, lightweight alternative to metal components in demanding industrial environments while offering an economical price point compared to many high-performance engineering plastics.
Acetal exhibits excellent mechanical strength, low moisture absorption, and outstanding resistance to wear and fatigue. Its naturally low coefficient of friction enables smooth operation in moving assemblies while minimizing wear on mating surfaces. Precision manufacturing ensures consistent diameter, sphericity, and surface finish, delivering reliable performance in both static and dynamic applications.
Delrin POM precision balls are widely used in bearings, ball valves, check valves, pumps, conveyors, flow control systems, and precision mechanical assemblies where low friction, dimensional accuracy, and long service life are essential.
