About CeramicSpeed's coating:
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 the CeramicSpeed 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.
