POM and PA materials have good mechanical strength and wear resistance, making them suitable for making relatively precise plastic bearings. The working temperature ranges from -60 ℃ to 100 ℃, and the surface strength is high and smooth, with basically no 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. Among them, 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 retainer is made of glass fiber reinforced nylon 66 (GRPA66-25). Balls are: glass ball bearings, stainless steel balls, or ceramic balls, which perform well in alkaline environments but are not suitable for operation in acidic and corrosive environments.
Features of Plastic Ring with Glass Ball Bearings :
1. It has high rigidity and hardness, and even at low temperatures, it has high impact strength;
2. Excellent elasticity and good creep resistance;
3. High heat resistance stability and excellent dimensional stability;
4. Good sliding performance and wear resistance;
5. Physiologically inert, suitable for contact with food.
6. Not resistant to strong acids and oxidants, poor adhesion to paint.
Application of Plastic Ring with Glass Ball Bearings :
Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorative building materials.
In recent years, engineering plastic products have been increasingly widely used due to their excellent performance. Engineering plastics have broad application prospects in bearings, and plastic bearings are becoming increasingly popular among users.
Due to its excellent self-lubricating, wear-resistant, low friction, and special anti bite properties, engineering plastics can work normally even under poor lubrication conditions, making them ideal as bearing materials.
