1. 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 made of materials suitable for precision machining are used as a whole. Based on the traditional advantages of plastic bearings, they can be used in precision and high-speed operating conditions. Generally, the inner and outer rings are made of POM, PPS, or PEEK, and the cage is made of glass fiber reinforced nylon 66 (RPA66-25) or PEEK. The rolling elements are glass balls, stainless steel balls, or ceramic balls.
2. Corrosion-resistant plastic bearings have multiple material solutions for different application conditions, and can operate freely even in the most severe acid / alkali / salt / solvent / oil / gas / seawater erosion, ensuring ideal durability and expectations life.
3. Acid and alkali resistant plastic bearings
HDPE, PE, 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, of which PTFE can be used for All concentrated acids and bases, including HF and fuming sulfuric acid and nitric acid (more than 98%).
4.High temperature resistant plastic bearing
PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyetheretherketone), PI (polyetherimide), etc. have all proven to be ideal materials for making high-temperature plastic bearings, where PI can be used at a long-term temperature of 290 It can be used under the environment of ℃, and the short-term temperature resistance can reach 350 ℃. It is the best type of high temperature performance among all known engineering plastics.
5. Plastic bearing seat and plastic outer spherical bearing. Plastic tapered bearing is unique in light weight, easy to install, corrosion-resistant and maintenance-free. At the same time, it has the vibration damping and impact resistance properties not commonly found in cast iron seats or stamping seats. With the continuous development of new materials, more and more widely used in engineering.
