Plastic bearings and metal sliding bearing the following differences:

1, the single direction thrust ball bearing are lubricating material, long service life. The metal sliding bearing lubrication layer is only 0.003 mm of PTFE surface, thin layer when the friction after it proclaims the end of the service life; 2, plastic bearings use will not happen in phenomenon of rust and corrosion resistance, and metal type of bearing is easy to rust cannot be applied to chemical liquid; 3, plastic lighter than metal bearing quality, it is more suitable for modern lightweight design trend; 4, rolling mill bearing manufacturing cost is relatively lower metals; Plastic bearings is the injection molding processing and become more suitable for mass production; 5, plastic bearings in operation without any noise, has a certain vibration absorption function; Due to plastic bearing is metal sliding bearing has many advantages, the production of plastic bearing is expanding increasingly, the use of plastic bearing situation is outspread, from fitness equipment to the office equipment and automobile industry, and so on all use plastic bearings, run on the roads of the car was not to use plastic bearings. Plastic bearing the market foreground is wide!
