Enduro Bearings 6903 LLU MAX BO - ABEC 3 MAX - Black Oxide (radial) - 17x30x7

BLACK OXIDE: Enduro bearings use races made from a 52100 chromium alloy and high-quality carbon, which has undergone both 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 ensures easy installation. The races are further polished after treatment to ensure the smoothest possible surface. These are the best bearings for the rear suspension. LLU : Similar to our LLB seals, the LLU is a contact seal where the double "lips" sit in a groove of the inner ring. Guaranteeing a better seal, these seals are ideal for suspension pivots or headsets that are constantly in contact with salt, sweat, and dust. This improved sealing and the 2 "lips" help retain 90% of the grease we use on the bearings, thus protecting it from moisture and continuously lubricating the balls and the race.
