Enduro bearings MR 22379 LLB - ABEC 3 (radial) - 22x37x9

ABEC 3: A standard value used to measure the surface tolerance of rolling bearings. There are five classes: 1, 3, 5, 7, and 9. The higher the ABEC class, the greater the precision, efficiency, and speed capacity, but the highest ABEC classes are not necessarily the fastest rotating components. All quality manufacturers worldwide use at least ABEC 1 as standard. At Enduro, the minimum standard is ABEC 3. ABEC 3: Steel balls Grade 10. Race made of 52100 chrome alloy and high carbon. ABEC 3 standard. Depending on their application, these bearings use LLU or LLB seals; even when marked with 2RS. LLB: Our most popular seal, consisting of a rubber finish with a metal core. Unlike the standard 2RS, we go a step further by machining a recess 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 rubbing against an uneven surface, the LLB type uses 2 sealing lips, fine as a razor blade that glides 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.
