Enduro bearings mr 19285 llb - abec 3 (radial) - 19x28x5

ABEC 3: A standard value used to measure the tolerance of the surface of the 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 parts. 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. Raceway in a 52100 chrome alloy and high-carbon steel. 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 mechanically placing a notch in the inner ring, where the seal can rotate with optimal efficiency and resistance to a lesser bearing. Rather than a single "lip" of a thick seal rubbing against an uneven surface, the LLB type uses 2 lips of seals, fine as a razor blade that glides into a notch 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.

Due to its unique size, it is often used as a hub bearing, especially for Fulcrum rear wheels. The Enduro line offers bearings in high-carbon chrome steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Designed with deep-groove races to accommodate larger balls, these bearings feature double lip seals that run in micro-grooves for full labyrinth sealing, ensuring long life and superior protection against the elements. Static load capacity is 375 lbf / 1.67 kN, weight 9.46 grams.
