1.Plastic bearings are made entirely of lubricating materials, with a long service life;

2. Plastic bearings will not rust and are resistant to corrosion during use, while metal bearings are prone to rust and cannot be used in chemical liquids;
3. Plastic bearings are lighter in weight than metals, 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 made by injection molding and are suitable for mass production;
5. Plastic bearings have no noise during operation and have a certain degree of vibration absorption function;
6. Plastic sliding bearings are suitable for high and low temperature work -200~+250 degrees;
