Enduro - bearing mr 17287 llb 17x28x7 ceramic hybrid abec 5

The XD-15 combines a hardened outer cage with silicon nitride ceramic balls, oversized in an exclusive working method that ensures a very high quality bearing. These bearings are 5X more resistant to corrosion than 440C stainless steel balls. These bearings rotate with a minimum of resistance compared to anything we have developed to date, with oversized Grade 3 ceramic balls. LLB: Our most popular seal, consisting of a rubber finish with a metal core. Unlike standard 2RS, we go a little further by machining a recess in the inner ring, where the seal can rotate with excellent efficiency and resistance to a lesser bearing. Rather than a single "lip" of a thick seal that rubs against an uneven surface, the LLB type uses 2 sealing lips, thin as a razor blade that slides into a recess with light contact. The outer "lip" keeps water and impurities out, while the inner seal retains grease for smooth rotation and long intervals between maintenance.
