Plastic Bearing

The plastic bearings used can generally be divided into plastic rolling bearings and plastic sliding bearings; the working principle of plastic rolling bearings and plastic sliding bearings can be distinguished by their names. The friction that occurs when plastic rolling bearings is working is rolling friction, while plastic sliding bearings are working. What happens is sliding friction; the magnitude of rolling friction mainly depends on the manufacturing accuracy; and the magnitude of friction of plastic sliding bearings mainly depends on the material of the sliding surface of the bearing


Plastic sliding bearings have the following characteristics:

1. The whole plastic bearing is made of lubricating material, with long service life;

2. Plastic bearings will not rust and are resistant to corrosion during use, while metal bearings are easy to rust and cannot be used in chemical liquids;

3. The quality of plastic bearings is lighter than that of metal, which is more suitable for modern lightweight design trends;

4. The manufacturing cost of plastic bearings is lower than that of metals; plastic bearings are processed by injection molding and are more suitable for mass production;

5. The plastic bearing has no noise during operation and has a certain vibration absorption function;

6. Plastic sliding bearings are suitable for high and low temperature work -200~+250 degrees;
