The characteristics of plastic bearings

SINO BEARINGSAug 02, 2022

The advantages of plastic bearings

1. The whole plastic bearing is lubricated material and has a long service life.

2. Rust and corrosion resistance will not occur in the application of plastic bearings, while metal bearings are easy to rust and can not be used in chemical liquids.

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

4. The manufacturing cost of plastic bearings is lower than that of metal materials; Plastic bearings are produced by injection molding and relatively suitable for mass production and manufacturing.

5. Plastic bearings have no noise in operation and have certain vibration absorption function.

6, plastic sliding bearing is suitable for high and low temperature operation -200 ~ +250 degrees.

The disadvantages of plastic bearings

1. For other bearings, plastic bearings have poor high temperature resistance.

2. Plastic bearing has low speed, low load and poor mechanical performance.
