The Coated Advantage
6-Year Warranty Program
CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our proprietary coating features several attributes that improve the longevity of CeramicSpeed Bearings. The increased hardness of the races, combined with the smoothness of theCeramicSpeed Balls results in virtually no wear on the bearing.
Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings.
Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.
Like all CeramicSpeed Bearings, our coated products are handbuilt in Denmark. Building a coated bearing adds a number of extra steps to the process. The CeramicSpeed balls and steel races are matched to the micron after which, each set of races is coated. The races are kept together in pairs through the entire process and after coating, each set needs to pass the quality control before they go into production.
