- Precision plastic bearings Precision plastic bearings provide improved precision and tolerances over conventional plastic bearings. The inner and outer rings, rolling elements and cages are made of materials suitable for precision machining. On the basis of maintaining the traditional advantages of plastic bearings, they can be applied to precision and relatively high-speed operating conditions. Generally, the inner and outer rings are made of POM, PPS, or PEEK, the cage is made of glass fiber reinforced nylon 66 (RPA66-25), or PEEK, and the rolling elements are glass balls, stainless steel balls or ceramic balls.
- Corrosion-resistant plastic bearings There are a variety of material solutions for different application conditions, even in the most severe acid/alkali/salt/solvent/oil/gas/sea water corrosion, it can still operate freely, ensuring ideal durability and expected life.
- Acid and alkali resistant plastic bearings HDPE, PE, UHMWPE materials have been proved to be used in relatively weak acid-base cross environment (30% CuCl2 solution and 30% NaOH solution test OK), PVDF and PTFE materials can be used in strong acid and strong alkali environment, of which PTFE can be used All concentrated acid and alkali occasions, including HF and fuming sulfuric acid nitric acid (above 98%), etc.
- High temperature resistant plastic bearing PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyetheretherketone), PI (polyetherimide), etc. have all proved to be ideal materials for making high-temperature plastic bearings, of which PI can be used at a long-term temperature of 290 When used in an environment of ℃, the short-term temperature resistance can reach up to 350℃. It is the best high-temperature performance among all known engineering plastics.
- Plastic bearing housing and plastic outer spherical bearing Plastic seated bearings are unique in light weight, easy to install, corrosion-resistant, and free from maintenance. At the same time, they have vibration-reducing and impact-resistant properties that common cast iron seats or stamping seats do not have. With the continuous development of new materials are more and more widely used in engineering.
