Our metric acetal precision balls combine low friction, wear resistance, and dimensional stability for smooth, consistent movement in mechanical assemblies. Made from polyoxymethylene (POM), also known as polyacetal, these lightweight plastic balls offer a practical alternative to metal balls where reduced weight and resistance to rust are priorities.
POM’s low moisture absorption helps limit dimensional changes in humid environments, while its strength and rigidity support repeated mechanical contact. These precision plastic balls are suitable for applications such as bearing assemblies, check valves, detent mechanisms, and sliding components, subject to operating loads and fluid compatibility.
