Applications‌: widely used in bearings, industrial machinery, mining equipment, and automotive hubs.Specifications: 19.05mm/20.0mm/22.225mm/25.0mmItem: POM Plastic BallMaterial: (Polyoxymethylene)Level: GO-G3 ± (0.01-0.05mm)Density: Around 1.4g/cm3High-precision grades for metrology.

• Performance: Polyoxymethylene oxide (POM), also known as Saigang or special steel.
• Has good physical, mechanical, and chemical properties, especially excellent friction resistance.
• It is similar to nylon, but slightly harder, denser, quieter, and has lower friction. It can be used for a long time in the temperature range of -40-130 ° C.
• Its wear resistance and self-lubricating properties are superior to most engineering plastics, and it also has good oil and peroxide resistance.
• Application: Typically used for sliding devices on tables and drawers, bearings, rollers, valves, electronic devices, and sailboat equipment.
