- Precision plastic bearings Precision plastic bearings have improved precision and tolerances compared to traditional plastic bearings. The inner and outer rings, rolling elements and cages are made of materials suitable for precision machining. While maintaining the traditional advantages of plastic bearings, it can be used in precision and higher-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, which can still operate freely even in the most severe acid/alkali/salt/solvent/oil/gas/seawater erosion, ensuring ideal durability and life expectancy. 3.Acid and alkali resistant plastic bearings HDPE, PE, and UHMWPE materials have been proven to be used in relatively weak acid-base cross environments (30% CuCl2 solution and 30% NaOH solution test OK). PVDF and PTFE materials can be used in strong acid and alkali environments, among which PTFE can be used All concentrated acid and alkali situations, including HF and fuming sulfuric acid and nitric acid (more than 98%), etc.
- High temperature resistant plastic bearings PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyetheretherketone), PI (polyetherimide), etc. have all proven to be ideal materials for making high-temperature plastic bearings. PI can be used at long-term temperatures 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 seats and plastic outer spherical bearings Plastic seated bearings are uniquely lightweight, easy to install, corrosion-resistant and maintenance-free. They also have vibration-damping and impact-resistance properties that common cast iron seats or stamped seats do not have. With the continuous development of new materials, they are increasingly being used in engineering.
