Plastic bearing POM6901
Plastic bearings have good mechanical strength, abrasion resistance, self-lubricity, high and low temperature resistance, as well as acid and alkali corrosion resistance, and light weight, low noise, can be used in resistance to magnetoelectric insulation, acid, alkali, seawater, chemical washing, transmission and other ordinary bearings can not adapt to the environment.
Application fields of plastic bearing: 1. Medical instruments, cryogenic engineering, optical instruments, food processing machinery. 2, in the petroleum, chemical, textile industry, machinery, food, need to be flammable, explosive, strong corrosion, vacuum, electrical insulation, no magnetic, dry friction and other special working conditions.
POM and PA are the most commonly used plastic bearing materials. The working temperature ranges from -60 ° c to 100 ° c. The surface strength is high and smooth, and basically no tension occurs. POM plastic bearing is one of the most widely used plastic bearings. Generally, POM or PA is used for inner and outer ball materials, and nylon 66 (grpa66-25) reinforced with glass fiber is used for cage. The ball ball is glass ball, stainless steel ball or ceramic ball. This kind of bearing performs well in alkaline environment, but is not suitable for operation in acidic corrosion environment.
