POM and PA materials with good mechanical strength and wear resistance, suitable for the production of more sophisticated plastic bearings, working temperature from -60 ℃ ~ 100 ℃, 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 applied to high speed. Which POM plastic bearings plastic bearings in all the most widely used, general materials used inside and outside the ball POM or PA, Cage made of glass fiber reinforced nylon 66 (GRPA66-25). Ball glass balls, stainless steel balls or ceramic balls, bearing alkaline environment, good performance, but not suitable for running four point contact ball slewing bearing under acidic corrosive environments.

1 the rigid, high hardness, even at low temperatures, high impact strength;
2 excellent flexibility, good creep resistance;
3 high thermal stability and very good dimensional stability;
4 good sliding properties, wear;
5 physiologically inert, suitable for food contact.
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 materials have been shown to cross for the relatively weak acid environment (30% Cucl2 solution and 30% NaoH solution test OK) so for most acid / base / salt / solvent / oil / gas and seawater corrosion environment. With the general plastic bearings for oil-free self-lubricating, anti-magnetic insulation properties, but lower mechanical strength, easily deformed, so this type of anti-acid plastic bearings do not apply to larger loads and higher speeds, in order to overcome such antacid alkali plastic bearings shortcomings. In comparison, the use of construction machinery bearing UPE material has better strength, low friction characteristics and low temperature application characteristics (down to -150 ℃), the general inner and outer ring material HDPE, PP or UPE, cage materials using HDPE, PP or UPE, ball glass ball, stainless steel balls or ceramic balls. Such anti-acid bearing overall performance will be greatly improved.
