A precision plastic bearings

Precision plastic bearings, has improved the precision and tolerances than traditional plastic bearings. The overall use of materials suitable for precision machining inner and outer ring, rolling element and cage can be app lied on the basis of maintaining the traditional advantages of plastic bearings, precision and higher speed operation conditions. General inner and outer ring material with POM, PPS, PEEK, glass fiber reinforced nylon 66 (RPA66-25), or PEEK, rolling body for glass balls, stainless steel balls or ceramic ball cage.roller thrust bearings
(2) corrosion-resistant plastic bearings

Solutions for a variety of materials for different application conditions, even in the most severe erosion of acid / base / salt / solvent / oil / gas / seawater can still operate freely, and to ensure that the desired durability and life expectancy.tool bearings

Acid and alkali resistant plastic bearings

HDPE, PE, UHMWPE materials have proved can be used for a relatively weak acid-base cross-environment (30% CuCl2 solution and 30% NaOH solution test OK), acid and alkali environment, PVDF and PTFE material, in which the PTFE can be used to concentrated acid and concentrated alkali occasions, including HF and fuming sulfuric acid, nitric acid (98% or more).cylindrical bearings

(4) high-temperature plastic bearings

PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyether ether ketone), PI (polyetherimide) have all proved to be an ideal material for the production of high-temperature plastic bearings, in which the PI can be long-term temperature of 290 ℃ environment, short-term temperature resistance up to 350 ° C is the best kind of all known engineering plastics, high temperature performance.

(5) plastic bearing and plastic spherical bearings

Plastic tape bearing a unique weight is light, easy to install, corrosion resistant, maintenance-free, while commonly used cast iron o r stamping seat does not have a damping shock resistance. With the continuous development of new materials are increasingly widely used in engineering.
