Self-aligning roller bearing high polymer material performance

On June 19, wafangdian bearing the authors explain for you: spherical roller bearing high polymer material performance polymer material performance refers to the interpretation of spherical roller bearing is based on polymer materials, polymer material is made of the relative molecular mass higher compounds material, including rubber, plastics, fibers, coatings, adhesives and polymer matrix composites, polymer is in the form of existence. Therefore, relative to other material physical properties and chemical properties of polymer material is better, the concrete has the following four performance. 1, spherical roller bearing the performance of polymer material by polymer molecules is a good insulation, insulation insulation performance and ceramics. Also has good for heat and sound insulation performance. 2, heat resistant thermosetting plastic heat resistance is higher than thermoplastics. Commonly used thermoplastic plastics such as polyethylene, PVC, nylon, long-term use of temperature below 100 ℃; Thermosetting plastics such as bakelite is 130 ℃ ~ 150 ℃; High temperature resistant plastic such as silicone plastic, can be used in 200 ℃ ~ 300 ℃. 3, spherical roller bearing high polymer material performance of the corrosion resistance of polymer chemistry stability is high. They are resistant to water and inorganic reagents, acid and alkali corrosion. Is known as the plastic of the king of ptfe, in particular, is not only strong corrosive such as strong acid, strong alkali resistance, even in the boiling of aqua regia is also stable. One of the advantages of good corrosion resistance is plastic. 4, aging aging refers to the polymer in the process of long-term use and storage, due to various factors, the effect of performance deterioration over time, the process of gradually lost use value. The main performance: rubber brittle crack or become soft, sticky; Plastic is fading, lose luster and cracking. These phenomena are irreversible, a major drawback of aging is polymer. Bearing is comfortable and durable
