Kaelalaager CeramicSpeed 1-1/2" Coated Trek 40x51x6,5mm 36/36 degrees (103805)

The CeramicSpeed Headset Bearing 1-1/2" is compatible with TrekCeramicSpeed Coated BearingsSpecifications: 40x51x6,5 mm, 36/36 degreesRELATED TECHNICAL INFORMATION:All CeramicSpeed COATED products are covered by a lifetime warranty. 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 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 HEREMaintenance of CeramicSpeed Coated BearingsCoated 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. Just as we do with our standard bearings, we recommend to always lubricate the bearings with our special grease to achieve optimal performance in terms of low friction and longevity.For all training and racing applications, we recommend the use of CeramicSpeed All-Round Grease. For the lowest friction possible, we recommend the use of our TT Grease. However, compared to the standard All-Round Grease, the TT Grease has a shortened lifetime and therefore, it requires more frequent application.Lifetime Warranty of CeramicSpeed Coated BearingsLike 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.CeramicSpeed Coated Bearings are available for Pulley Wheels, Bottom Brackets, Wheel Kits, the Oversized Pulley Wheel Systems and Headsets.
