, POM plastic bearings, the the PP plastic bearing (POM-Guo -1-3-7-3829-0634)
POM and PA material with good mechanical strength and abrasion resistance, suitable for the production of precision plastic b earings, operating temperature from -60 ° C at 100 ° C, the surface of high strength and smooth, and basically not tension, good self-lubricating performance and low coefficient of friction, on the basis of maintaining the traditional advantages of plastic bearings can be used in precision and higher speed operation. POM plastic bearings are the most widely used plastic bearings a general internal and external ball made of POM or PA cage with glass fiber reinforced nylon 66 (GRPA66-25). Ball glass balls, stainless steel balls or ceramic ball, such bearing alkaline environment under good but not suitable for running in acidic corrosive environment.ball roller bearing
Features:
Rigid, high hardness, even at low temperatures, high impact strength;
Excellent elasticity, good creep resistance;
3 high heat stability and very good dimensional stability;bearings high speed
4 good sliding properties, wear resistance;
Physiologically inert, suitable for contact with food.
Even in strong acid and strong oxidizing agents, poor adhesion paint
Main purposes: mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorating materials.
HDPE, PP, UPE material has proved for the relatively weak acid cross-environment (30% Cucl2 solution of 30% NaoH solution test OK) it applies to most of the acid / base / salt / Solvent / oil / gas and seawater corrosion environment. With general plastic bearings of non-oil self-lubricating, anti-magnetic electrical insulation performance, low mechanical strength, easily deformed, and therefore does not apply to such anti-acid-base plastic bearings for greater load and higher speed, to overcome this kind of antacid alkali plastic bearings shortcomings. In comparison, the use The the UPE materials have better s trength, low friction characteristics and low-temperature characteristics (minimum to -150 ° C), the general inner and outer rings made of HDPE, PP or UPE, maintaining the frame material used of HDPE, PP, or UPE, ball glass ball, stainless steel balls or ceramic balls. Such anti-acid-base bearing overall performance will be greatly improved.
Features:
A good corrosion resistance, in a certain temperature and concentration within the ability of various corrosive media and organic media
2 high mechanical strength, high toughness cut can be maintained at the temperature of liquid nitrogen (-196 ℃)
3 good self-lubricating properties, high abrasion resistance
Anti-adhesion ability.
Low water absorption, excellent electrical insulating properties
6 good performance against high energy radiation
Main purposes: mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorating materials.thrust bearing
, PTFE high temperature corrosion-resistant plastic bearings
PTFE and PI as emerging engineering plastics material, proved to be better dimensional stability and resistance to high temperature of the mechanical strength of all known engineering plastics, PTFE long-term use temperature of 260 ℃, PI long-term use temperature is up to 300 ℃ and outer ring material with excellent resistance to corrosion, acid corrosion in the moderate-intensity environment can still operate freely, it is generally used for the production needs choice of PTFE or PI, ball generally Zro2 or Si3N4 ceramic ball. Bearing precision operation in a relatively harsh environment, the drawback is the material itself is more expensive, it is the use of high cost.
