ABEC 3 LLB: Our most popular seal, consisting of a rubber finish with a metal core. Unlike the standard 2RS, we go a bit further by machine-milling a groove into the inner ring, where the seal can rotate with excellent 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 razor-thin sealing lips that slide into a groove 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.
