POM balls are widely used in low-friction rolling, guiding and mechanical contact applications requiring quiet operation and stable wear performance.
POM balls are commonly used in rolling, sliding and guiding applications requiring low friction and quiet operation.
POM balls, also commonly referred to as acetal balls, are widely used in valves, rollers and mechanical moving assemblies.
Compared with metallic balls, POM balls provide quieter operation, lower friction and good wear resistance, making them suitable for rolling, guiding and sliding applications.
POM balls also maintain good dimensional stability and low moisture absorption in many industrial working environments.
POM balls are suitable for low-load rolling, guiding and general valve applications, but they should not be used in high-temperature, high-pressure or highly corrosive valve systems without confirming the working conditions.
