As the most versatile plastic, POM/PA/PET has good mechanical strength, fatigue resistance and wear resistance. Due to the self-lubrication and low friction coefficient of the material itself, POM/PA/PET is suitable for the production of light weight, low noise, high speed precision plastic rolling bearings. POM bearings are good in alkaline environment, but not suitable for long-term operation in acidic environment, long-term continuous use temperature -50℃ -- 110 ℃; PA bearing is allowed to run in alkali, weak acid and detergent corrosive environment for a long time, long-term continuous use temperature of -40℃ -- 90℃; PET bearings have excellent wear resistance, acid corrosion resistance, radiation resistance, stable to organic solvents and oil, but not heat resistant water immersion, alkali resistance. Long-term continuous use of temperature -20℃ - 115℃.

UPE, HDPE, PP material has good wear resistance and low temperature application characteristics, can be used for relatively weak alkali cross environment, possess general plastic oil-free self-lubricating bearings, magnetic properties, such as electrical insulation resistance, suitable for most alms acid/alkali/salt/solvent/oil/gas and sea water corrosion environment, but this kind of plastic bearings with low mechanical strength, easy to deformation, Not suitable for large load and high speed. Among them, UPE material has the best abrasion resistance and low temperature resistance among known plastics, and its long-term continuous use temperature is -150℃ -- 90℃.

PTFE, PVDF and PCTFE materials have good corrosion resistance, high temperature resistance and wear resistance, can be used in all strong acid and strong alkali occasions, including hydrofluoric acid (HF) and fuming nitric acid (more than 98%). PTFE has the best corrosion resistance among all known engineering plastics, and the long-term use temperature can reach 250℃, but THE mechanical strength of PTEF material is very low, and the stability of the size is poor; PVDF and PCTFE materials have high mechanical strength, good size stability, PVDF long-term use temperature can reach 180℃, PCTFE long-term use temperature can reach 170℃.

PEEK, PI and PPS as emerging engineering plastics materials, in all known engineering plastics have extremely high mechanical strength and dimensional stability, strong corrosion resistance, and the best high temperature resistance, almost can operate in all acid and alkali corrosion environment. The long-term service temperature of PEEK and PPS is 260℃, and the long-term service temperature of PI is up to 300℃.

With the increasing complexity of mechanical equipment, standard mechanical equipment bearings have been unable to meet the needs of products, in the face of the different needs of different users, we can provide the products you need for your requirements. If you are interested, please inform us of the product requirements or drawings, we will provide you with special bearings for special occasions.
