What are the characteristics of pom bearing?

Pom bearing has the following characteristics:
1. The whole pom bearing is made of lubricating material with long service life;
2. The pom bearing will not rust and is corrosion-resistant, while metal bearings are easy to rust and cannot be used in chemical liquids;
3. The weight of pom bearing is lighter than metal, which is more suitable for the trend of modern lightweight design;
4. The manufacturing cost of pom bearing is lower than that of metal; plastic bearings are made by injection molding and are more suitable for mass production;
5. The pom bearing has no noise during operation and has a certain vibration absorption function;
6. Pom bearing is suitable for high and low temperature work -200～+250 degrees;

The 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 made must be self-lubricating to improve its comprehensive wear resistance; for example, the common plastic linear bearing in the market is The material is made of lubricants and reinforced fiber modified engineering plastics, and its wear resistance is very good;

Because pom bearings have many advantages over metal sliding bearings, the output of plastic bearings is expanding day by day, and the use of pom bearings is also continuously extending. Plastic bearings are used in fitness equipment, office equipment, and the automotive industry. There is no car on the road that does not use plastic bearings.

The pom bearing material has good mechanical strength and wear resistance, and is suitable for making more precise plastic bearings. The working temperature is from -60°C to 100°C. The surface strength is high and smooth, and there is basically no tension. It has good self-lubricating properties. And low friction coefficient, on the basis of maintaining the traditional advantages of pom bearing, it can be applied to precision and higher speed operation.

Pom bearing is the most widely used of 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 balls are glass balls, stainless steel balls or ceramic balls. This kind of bearing performs well in alkaline environments but is not suitable for operation in acidic corrosive environments.

Features of pom bearing:
1. High rigidity, high hardness, high impact strength even at low temperature;
2. Excellent elasticity and good creep resistance;
3. High heat 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 bearing:
Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decoration building materials
