Plastic bearings
Currently used plastic bearings rolling bearings in general can be divided into plastic plastic sliding bearings ; Plastic Rolling plastic working principle of the sliding bearing can be distinguished by its name , the rolling bearing friction when the plastic working is a rolling friction , the bearing slide and the plastic occurs when the sliding friction ; rolling friction depends mainly on the size and manufacturing precision ; while the plastic sliding bearing friction bearing material depends primarily on the size of the sliding surface .

CSB-EPB series plastic plain bearings
Face plastic plain bearings are generally self-lubricating ; plastic plain bearings are generally used relatively good performance engineering plastics ; more specialized manufacturers generally have a self-lubricating plastic modification technology , through the fiber , specialty lubricants, glass beads and so on self -lubricating plastic reinforced modified so as to achieve a certain performance , then use the modified plastics processing into self-lubricating bearings by plastic injection molding, plastic polymer plain bearings currently more widely used is the CSB-EPB plastic plain bearings .
  CSB-EPB most versatile plastic plain bearings
  CSB-EPB14A high- speed line with FDA plastic plain bearings
CSB-EPB series plastic plain bearings have the following characteristics:
1 , plastic bearings are lubricated material overall , long life ;
2 , does not occur in the use of plastic bearings rusting and corrosion , rust and metal bearing chemical solution can not be used ;
3 , lighter than metal bearing quality plastic , which is more suitable for modern lightweight design trends ;
4 , plastic bearings manufacturing costs are lower than the metal ; plastic bearings used in injection molding processing is more suitable for mass production ;
5 , the plastic bearing no noise in operation, having a vibration absorbing function ;
6 , plastic plain bearings suitable for high temperature -200 to +250 degrees work ;
Plastic plain bearings can be made not only the shape of the sleeve can also be made of plastic plain bearings straight , but only materials must be improved in order to improve its self-lubricating integrated wear ; such as the current common market CSB- LIN is a plastic material through linear bearings and lubricants reinforcing fibers modified with plastic, its wear resistance is excellent ;
  CSB-LIN series of wear-resistant plastic linear plain bearings
As the plastic sliding bearings over the metal sliding bearings there are many advantages, the current production of plastic bearings are increasingly expanding the use of plastic bearings are constantly extending the occasion , from fitness equipment to office equipment and automotive industries , etc. are used in the plastic bearings currently traveling on the highway without using a car without plastic bearing.

POM plastic bearings , PP plastic bearings
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 no 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 . 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 to perform well , but is not suitable for running in an acidic corrosive environments .
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 , so this type of anti-acid plastic bearings do not apply to larger loads and higher speeds, in order to overcome such antacid plastic bearing base disadvantages . In comparison, the use of UPE material will have better strength , low friction characteristics and low temperature application characteristics (down to -150 ℃), generally inside and outside the ring material HDPE, PP or UPE, cage materials using HDPE, PP or UPE, balls glass balls, stainless steel balls or ceramic balls. Such anti-acid bearing overall performance will be greatly improved .
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 ℃)
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 ℃, PI long-term use temperature is as high as 300 ℃ , and it has excellent corrosion resistance in acid corrosion environment of moderate intensity can still operate freely, it is generally needed for the production of PTFE outer material selection or PI, 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
