1. Corrosion-resistant plastic bearings <br> There are various data solutions for different alignment conditions. INA bearings can work even in the most stringent acid/alkali/salt/solvent/oil/gas/seawater corrosion; Ensuring the durability and expected life expectancy of the ambition. It is usually used in medical occupations and food occupations.
2, fine plastic bearings <br> fine plastic bearings; finer than the traditional plastic bearings and public service improvements. All choose the appropriate internal and external rings for the processing of fine materials; roll and stand; in the traditional advantages of plastic bearings On the basis of; can be used for fine and high-speed working conditions. Usually POM; PPS; or PEEK for internal and external ring data; glass fiber reinforced nylon 66 (RPA66-25); or PEEK; glass ball Stainless steel ball or ceramic ball.
3, high temperature resistant INA bearing plastic bearings PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyether ether ketone), PI (polyetherimide), etc. have proved to be the ambition of manufacturing high temperature plastic bearings In the meantime, PI can be used in a long-term temperature of 290 ° C; short-term temperature can reach up to 350 ° C. It is the best one of all known engineering plastics.
4, acid-resistant plastic bearings HDPE, PE, UHMWPE data has been proven to be used in a relatively weak acid-base intercalation environment (30% CuCl2 solution and 30% NaOH solution test OK), PVDF can be used in strong acid and alkali environment PTFE data, in which PTFE can be used in all concentrated acid and concentrated alkali applications, including HF and fuming sulfuric acid nitric acid (98% or more).
5, plastic bearing housing and plastic outer spherical bearing <br> Plastic bearing bearing is light and light; the device is simple; corrosion-resistant; free of protection; together with the common cast iron seat or stamping seat does not have the vibration and shock resistance. With the continuous development of new materials, it is increasingly used in engineering.
