Bearings ch mr 17287 llb - ceramic hybrid (radial) - 17x28x7

The XD-15 combines a hardened outer cage with silicone nitride ceramic balls, oversized in an exclusive way of working that ensures a very high quality bearing. These bearings are 5X more resistant to corrosion than 440C stainless steel balls. These bearings spin with minimal resistance than anything we've developed to date, using oversized Grade 3 ceramic balls. LLB: Our most popular seal, featuring a rubber finish with a metal core. Unlike the standard 2RS, we go a little further by machining a notch in the inner ring, where the seal can rotate with excellent efficiency and resistance compared to a lesser bearing. Rather than a single «lip» of a thick seal that rubs against an uneven surface, the LLB type uses 2 lips of seals, fine like a razor blade that slides in a notch with a light contact. The outer «lip» keeps out water and impurities, while the inner seal retains grease for smooth rotation and long intervals between services.

Si3N4 Ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. Radial bearing generally used as a hub bearing, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
