The XD-15 combines a hardened outer race with ceramic silicon nitride 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 run with less resistance than 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 optimal efficiency and resistance compared to an inferior bearing. Rather than a single "lip" of a thick seal rubbing against an uneven surface, the LLB type uses 2 sealing lips, fine like a razor blade that slides into a recess with light contact. The outer "lip" keeps water and impurities out, while the inner seal retains the grease for smooth rotation and long intervals between maintenance.
