Temat: Rolling Bearings feature polymer cages

SKF angular contact ball bearings and cylindrical roller bearings feature PEEK (polyetheretherketone) cages that are resistant to aggressive compressor-related gases, exhibit mechanical properties even at temperatures up to 200ºC, resist heat aging in aggressive media, and demonstrate tribological properties relative to wear resistance and low friction. Bearings suit compressor applications in wide range of industries including natural gas, chemical, and refrigeration.
