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. CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. The unique 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 unique coating is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.Longetivity comparison diagram: see HEREWithin comprehensive research and development 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.Friction comparison diagram (lower is better): see HEREAll Round Grease - Designed to suit the maintenance of CeramicSpeed Bearings, the CeramicSpeed All-Round Grease maximizes your bearings’ lifetime and performance. This type of grease is a low to medium viscosity lubricant and works as the best compromise between friction influence and lifetime. We recommend it for optimal use in dry and sunny weather conditions, where no or very little contamination threatens the bearing. The application covers mostly road riding conditions, however it can be used off-road in the same weather settings, on all types of CeramicSpeed Bearings. When lubricating your bearings, we recommend a fill rate of 60-80%.Maintenance of CeramicSpeed 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 completely eliminated.Depending on the riding conditions it is recommended once a year to re-grease your CeramicSpeed Bearings to achieve the best performance in terms of low friction and longevity.If used in very wet or muddy conditions, maintenance might be required more often.If high pressure washer is used, please do not point jet stream to any of bearings (headset, bottom bracket, wheel hub, full suspension links) as it may wash out the grease.
