Enduro bearings acb 6808 cc bo - abec 5 - black oxide (angular contact) - 40x52x6.5 (36x45°)

We do not offer bearings for low-end headsets. Instead, we start with chrome steel, Black Oxide A/C, and finally 440C stainless steel bearings. They are always constructed with the largest possible balls, and their double-lip seals are seated in a small recess for ultimate protection against sweat and the elements. They are 90% filled with high-pressure grease, so you don't have to wonder if there's grease inside. BLACK OXIDE: Enduro bearings use races made from 52100 chrome alloy and high-carbon steel, which have undergone thermal and cryogenic treatment. This means everything is brought to a temperature of –190°, which provides a certain hardness and thus reduces ball wear. We then give the bearing a magnetic treatment (black or Black Oxide color), which provides protection against corrosion and also makes installation easy. The races are further polished after treatment to create the smoothest possible surface. These are the best bearings for the suspension linkage.

This high-quality bearing measures 40mm x 52mm x 6.5mm with a contact angle of 36° x 45°, designed with anti-corrosion 52100 high-carbon chromium alloy races and grade 10 balls for reliable performance. The Black Oxide coating provides extra protection against rust and wear, ensuring everything continues to operate smoothly and for a long time. All Enduro Black Oxide headset bearings come with a two-year warranty. Known in the industry under part numbers such as HD 1404K, BAA0006K, MR-127, MR-196, MH-P25K, BAA1132, TH and MR019, this bearing is part of the advanced Enduro line, which surpasses standard specifications. Designed with larger balls and double-lip labyrinth seals, they offer maximum protection against dirt, moisture, and water, keeping the grease seals intact and the components running smoothly. The angular contact (A/C) design ensures that all balls distribute the load evenly, reducing wear and extending lifespan. Static load capacity is 917 lbf (4.08 kN), weight only 24.9 grams.
