1) Precision plastic bearing Precision plastic bearings, have the more exact rolling accuracy and more strict dimension tolerance. The proper material, which is prone to precision machining, is selected to make the inner ring, outer ring, balls and cage, could be used in precision and high-speed running applications.
2)Anti-Corrosion Plastic Bearings Various material such as; POM, PP, PA, PBT, UHMWPE, PTFE, PEEK may be selected for their resistance to chemicals aim at various anti-corrosion application, Such bearings can operate in liquids and contamination sensitive environments even eroded in the most inclemency acid/alkali/salt/impregnant/oil/gas/seawater. Generally materials are fit together as following:
3)Anti-Acid & Anti-Alkali Bearing HDPE, PE, UHMWPE are approved can be used in faintish acid and alkali environment. (30% CuCl2 solution and 30% NaOH solution is tested ok). PVDF AND PTFE can be used in strong acid and alkali environment. Therein? PTFE can be used in thick acid and alkali environment, including HF oleum and nitric acid.
4)High Temperature Application Plastic Bearings PVDF, PTFE (Teflon), PPS, PEEK, PI were approved which are the perfect material for high temperature application plastic bearings. Therein, PI can be used at 300? In long-term Short-term can endure 350? , which is the best one on the known project plastic.
5)Plastic Inserts & Plastic Pillow Blocks The plastics insert bearings specially have the performance of corrosion and wear resistance, reduce vibration and anti-bump, be freed from the maintenance and so forth, aim at working in different environment the material of PBT, UHMN, and PTFE can be provided as choice.
