POM PP PTFE PEEK plastic ball bearing

POM and PA materials have good mechanical strength and wear resistance. They are suitable for making relatively precise plastic bearings. The working temperature ranges from -60 °C to 100 °C. The surface strength is high and smooth, and there is basically no tension. The self-lubricating is good. Performance and low coefficient of friction, based on the traditional advantages of plastic bearings, can be applied to precision and high speed operation. Among them, POM plastic bearing is the most widely used one of all plastic bearings. Generally, the inner and outer ball materials are POM or PA, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The balls are glass balls, stainless steel balls or ceramic balls. These bearings perform well under alkaline conditions but are not suitable for operation in acidic corrosive environments.

HDPE, PP, UPE materials have been proven to be used in relatively weak acid-base cross-linking environments (30% Cucl2 solution and 30% NaoH solution tested OK) and are therefore suitable for most acids/bases/salts/solvates/oils/gases and Sea water corrodes the environment. It has the properties of oil-free self-lubricating and anti-magnetic electrical insulation of general plastic bearings, but its mechanical strength is low and it is easy to deform. Therefore, such acid-resistant plastic bearings are not suitable for large loads and high speeds, in order to overcome such acid resistance. Disadvantages of alkali plastic bearings. In comparison, UPE materials have better strength, low friction characteristics and low temperature application characteristics (down to -150 ° C). Generally, the inner and outer rings are made of HDPE, PP or UPE, and the cage materials are HDPE, PP or UPE, the ball is a glass ball, a stainless steel ball or a ceramic ball. This comprehensive performance of acid and alkali bearings will be greatly improved.
