CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our unique 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. The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results. 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. Maintenance of Coated Bearings Coated Bearings are more resistant to lack of lubrication when it comes to wear and damage on the bearing. Nonetheless, this does not mean that the need for maintenance is eliminated. However, compared to the standard All-Round Grease, the TT Grease has a shortened lifetime and therefore, it requires more frequent application. 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. CeramicSpeed Coated Bearings are available for Pulley Wheels, Bottom Brackets, Wheel Kits, the Oversized Pulley Wheel Systems and Headsets.
