Plastic Bearing Type
We can produce different type of plastic bearing with material POM ,PP PEEK ,PE.
POM plastic bearings, PP plastic bearings
POM and PA materials have good mechanical strength and wear resistance, suitable for making more precise plastic bearings, working temperature from -60 ℃ ~ 100 ℃, high surface strength and smooth, basically no tension, its good self-lubrication The performance and low friction coefficient can be applied to precision and higher speed operation on the basis of maintaining the traditional advantages of plastic bearings. Among them, POM plastic bearings are the most widely used among all plastic bearings. Generally, the inner and outer ball materials use POM or PA, and the cage uses glass fiber reinforced nylon 66 (GRPA66-25). The ball is a glass ball, stainless steel ball or ceramic ball. This type of bearing performs well in an alkaline environment but is not suitable for operation in an acidic corrosive environment. characteristic:
Application :
Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decoration building materials.
HDPE, PP, UPE materials have been proven to be used in relatively weak acid-base cross environments (30% Cucl2 solution and 30% NaoH solution test OK), so it is suitable for most acids / alkali / salt / solvent / oil / gas and Seawater corrodes the environment. It has the properties of oil-free self-lubrication and anti-magnetic electrical insulation of general plastic bearings, but the mechanical strength is low and it is easy to deform. Therefore, such acid-resistant plastic bearings are not suitable for larger loads and higher speeds. In order to overcome such acid resistance Disadvantages of alkaline plastic bearings. In comparison, using UPE material has better strength, low friction characteristics and low temperature application characteristics (down to -150 ℃), generally the inner and outer ring materials are HDPE, PP or UPE, the cage material is HDPE, PP or UPE, the ball is a glass ball, stainless steel ball or ceramic ball. In this way, the comprehensive performance of the acid-base bearing will be greatly improved. characteristic:

Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decoration building materials
PTFE high temperature and corrosion resistant plastic bearings
PTFE and PI, as emerging engineering plastic materials, have proven to have good mechanical strength, dimensional stability and high temperature resistance among all known engineering plastics
Plastic bearings
Among them, the long-term use temperature of PTFE reaches 260 ℃, the long-term use temperature of PI is as high as 300 ℃, and it has excellent corrosion resistance. It can still operate freely in medium-strength acid and alkali corrosion environments, so it is generally used for production. The material of the ring is PTFE or PI, and the balls are generally Zro2 or Si3N4 ceramic balls. The disadvantage of bearings that operate precisely in a harsh environment is that the materials are more expensive, so the cost of use is higher.
