Polymer bearings, ordinarily known as plastic bearings, are the most recent advancement in the bearings business. A heading is comprised of four unique parts: inward race, external race, confine, and balls. The mix of these parts as one permits smooth and contact free movement. In polymer bearings, the inward race, the external race, and the pen are altogether comprised of plastic and the material utilized for assembling balls relies upon the sort of uses and ecological conditions it gets exposed to. Materials that can be utilized to fabricate balls incorporate plastic, hardened steel, and glass. Polymer bearings give various focal points over different bearings. This incorporates protection from consumption, synthetic concoctions, and weakness, self-oil, lightweight, low co-effective of contact, and calm activity. Polymer bearings is a perfect alternative in applications where steel bearings can’t be utilized, inferable from their destructive inclinations.
Furthermore, they are economical than the other types of bearings. Therefore, these are used in various applications in industries such as food & beverages, textile, medical & pharmaceutical, and electrical. However, polymer ball bearings cannot be subjected to applications involving high loads and prolonged exposure to temperatures exceeding 300°F. This calls for need to use traditional bearings such as stainless steel bearings and ceramic bearings. Ceramic bearings offer numerous advantages. They overcome most limitations generally encountered in the other two bearings, and can be subjected to high temperatures up to 1800°F and high loads. Despite these advantages, ceramic bearings are used less, as they are expensive. Thus, polymer bearings are widely being used, as they are economical and offer large number of advantages. The market for polymer bearings is expected to expand at a steady pace owing to the increasing usage of these bearings in a large number of industrial applications.
Based on the type of ball used in the bearings, the market for polymer bearings can be segmented into plastic ball bearing, glass ball bearing, and stainless steel ball bearing. The choice of the material to be used for balls highly depends on the kind of conditions and applications the bearing is subjected to. Plastic balls are generally used when there is a need of light weight, noise free operation. Glass balls are employed when a comparatively lighter option is required in a metal free application. Glass balls also exhibit less magnetic properties.
Based on end-use industry, the polymer bearings market can be segmented into chemical industry, food & beverages industry, textile industry, and medical & pharmaceutical industry. The usage of polymer bearings is increasing across these industrial segments. The chemical industry segment of the polymer bearings market is anticipated to expand at a steady pace due to the growth in the chemical industry. The chemical industry is witnessing considerable growth due to growing market of pharmaceutical products and consumer goods.
Geographically, the market for polymer bearings can be divided into North America, Latin America, Asia Pacific, Europe, and Middle East & Africa. The polymer bearings market is likely to expand significantly in Asia Pacific owing to factors such as rapid industrialization and economic, infrastructural development in countries such as India, China, and Japan.
Key players operating in the polymer bearings market include Schaeffler Group, SKF, Timken Company, RKB Bearing Industries, NSK, and JTEKT Corporation.
