Introduction to Plastic Bearings POM plastic bearings, PP plastic bearings, POM and PA materials have good mechanical strength and wear resistance, suitable for making relatively precise plastic bearings. The working temperature ranges from -60 ℃ to 100 ℃, and the surface strength is high and smooth, basically without tension. Its good self-lubricating performance and low friction coefficient can be applied to precision and high-speed operation while maintaining the traditional advantages of plastic bearings. POM plastic bearings are the most widely used among all plastic bearings. Generally, the inner and outer ball materials are made of POM or PA, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The ball bearings are made of glass, stainless steel or ceramic balls, which perform well in alkaline environments but are not suitable for operation in acidic corrosive environments. Characteristics: 1. High rigidity, high hardness, even at low temperatures, high impact resistance; 2. Excellent elasticity and good creep resistance; 3. High heat resistance and excellent dimensional stability; 4. Good sliding performance and wear resistance; 5. Physiological inertia, suitable for contact with food. 6. Not resistant to strong acids and oxidants, with poor adhesion to paint. Main uses: mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorative building materials, medical equipment, environmental protection machinery, cleaning equipment, insulation machinery equipment, etc!
