POM plastic bearings , PP plastic bearing POM and PA materials with good mechanical strength and wear resistance , suitable for the production of more sophisticated plastic bearings, working temperature from -60 °C ~ 100 °C, high strength and smooth surface , basically does not appear tension , its good self-lubricating properties and low coefficient of friction , while maintaining the traditional advantages of plastic bearings on the basis of precise and can be used in high speed operation . Features: (1) rigidity, high hardness , even at low temperatures , high impact strength (2) good excellent elasticity , creep resistance ; (3) high thermal stability and very good dimensional stability ; (4)good sliding properties , wear resistance ; (5) physiologically inert , suitable for contact with food. (6) Even in strong acid and strong oxidizing agents, poor paint adhesion Main purpose : Mechanical and electrical equipment , fitness equipment , food machinery , furniture and decorating materials
HDPE, PP, UPE material has proven to be relatively weak acid cross- environment (30% Cucl2 solution and 30% NaoH solution tested OK) it is suitable for most acid / base / salt / solvent / oil / gas and seawater corrosion environment. With general plastic bearings oil-free self -lubricating, anti-magnetic insulation properties, but lower mechanical strength , easily deformed. In comparison, the use of UPE material will have better strength , low friction characteristics and low temperature application characteristics (down to -150 °C). Features: (1) good corrosion resistance at a certain temperature and concentration ability of various corrosive media and organic media (2) high mechanical strength , high toughness can be maintained cutting at liquid nitrogen temperature (-196 °C) (3)good self- lubricating, wear high (4) Strong anti- adhesion (5) low water absorption, excellent electrical insulation (6) good resistance to high energy radiation Main purpose : Mechanical and electrical equipment , fitness equipment , food machinery , furniture and decorating materials PTFE high-temperature corrosion-resistant plastic bearings PTFE and PI as a new plastic material , proved to be all known engineering plastics and high temperature mechanical strength, dimensional stability and better performance , in which long-term use temperature of PTFE 260 °C, PI long-term use temperature is as high as 300 °C , and which has excellent corrosion resistance. The ball is generally Zro2 or Si3N4 ceramic balls. In comparison the harsh operating environment of precision bearings , the drawback is due to the material itself is relatively expensive , so the higher cost
