Pom bearings have the following characteristics:
- 1. The whole pom bearing is made of lubricating material, which has a long service life;
- 2. Pom bearings will not rust and are corrosion-resistant, while metal bearings are prone to rust and cannot be used in chemical liquids;
- 3. The weight of pom bearing is lighter than that of metal, which is more suitable for the trend of modern lightweight design;
- 4. The manufacturing cost of pom bearings is lower than that of metal; plastic bearings are injection molded, which is more suitable for mass production;
- 5. The pom bearing has no noise during operation and has a certain vibration-absorbing function;
- 6. Pom bearings are suitable for high and low temperature work -200 ~ +250 degrees;
Pom bearing
This pom bearing can not only be made into the shape of a shaft sleeve, but also can be made into a plastic linear sliding bearing, but the premise is that the material must be self-lubricating to improve its comprehensive wear resistance; for example, the common plastic linear bearings on the market The bearing is made of lubricant and reinforced fiber modified engineering plastics, and its wear resistance is very good;
Since machining pom bearings have many advantages over metal sliding bearings, the output of plastic bearings is expanding day by day, and the uses of pom bearings are also expanding. Plastic bearings are used in fitness equipment, office equipment and the automotive industry. There is no car on the road that doesn’t use plastic bearings. pom bearing material has good mechanical strength and wear resistance, suitable for making more precise plastic bearings. Operating temperature is -60°C to 100°C. The surface strength is high and smooth, and there is basically no pulling force. It has good self-lubricating properties. And the coefficient of friction is low. On the basis of maintaining the traditional advantages, pom bearings can be applied to operations with higher precision and higher speed.
POM bearings are the most widely used of all plastic bearings. The inner and outer balls are generally made of POM or PA, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The balls are glass balls, stainless steel balls or ceramic balls. This type of bearing performs well in alkaline environments, but is not suitable for operation in acidic corrosive environments.
The characteristics of pom bearings
- 1. High rigidity, high hardness, high impact strength even at low temperature;
- 2. Good elasticity and good creep resistance;
- 3. High thermal stability and very good dimensional stability;
- 4. Good sliding performance and wear resistance;
- 5. Physiologically inert, suitable for contact with food.
- 6. Not resistant to strong acids and strong oxidants, poor adhesion to paint
The main purpose of pom bearings
Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decoration building materials
