Classification of still have a lot of plastic bearing, evidenced by using range knew about, small make up today to see or talk to everyone at ordinary times often often use a few plastic bearings.
1. Precision plastic bearing FAG Bearing Limiting Speed http://www.fagbearing-china.com/ .
Precision plastic bearings and precision than the traditional plastic bearings and tolerance. Overall adopt suitable for precision machining material inside and outside the ring, rolling elements and cage, on the basis of traditional advantage in keeping the plastic bearing, precision and can be applied to the working condition of high speed. Inside and outside the ring material commonly used POM, PPS, PEEK, or keep using glass fiber reinforced nylon 66 (RPA66-25), or PEEK, rolling body for the glass ball, stainless steel or ceramic ball.
2. The corrosion resistant plastic bearings
There are many material solution for different application conditions, even in the most severe acid/alkali/salt/solvent/oil/gas/water erosion can still function properly, ensure durability of the ideal and life expectancy.
3. The acid and alkali resistant plastic bearings
HDPE, PE, UHMWPE materials have shown can be used to relatively weak alkali cross environment (30% of CuCl2 test OK) solution and 30% NaOH solution, acid alkali environment can use PTFE material, PVDF and PTFE which can be used in strong acid and strong alkali all occasions, including HF and fuming sulfuric acid, nitric acid (98%), etc.
4. High temperature resistant plastic bearings
PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (poly (ether ether ketone), PI (such as poly (ether imide) are proved to be ideal material of making high temperature plastic bearing, the PI can be used under the temperature 290 ℃ environment for a long time, short term heat resistance up to 350 ℃. Is that all the engineering plastics in the high temperature performance is one of the best known.
5. Plastic housings and plastic outer spherical bearing
Plastic arrange ushering bearing with light weight, convenient installation, corrosion resistance, free from maintenance, at the same time with common cast iron or stamping a does not have the vibration shock resistance. With the continuous development of new materials are increasingly widely used in engineering.
