1, plastic bearings are lubricating materials, long service life;
2, plastic bearings will not rust in use and corrosion resistance, and metal bearings are easy to rust can not be used in chemical liquid;
3, plastic bearing quality is lighter than metal, which is more suitable for the modern lightweight design trend;
4, plastic bearing manufacturing cost is lower than metal; Plastic bearings are made of injection molding, which is more suitable for mass production.
5, plastic bearing in operation without any noise, has a certain vibration absorption function;
6, plastic sliding bearing suitable for high and low temperature work -200 ~ +250 degrees;
