Enduro bearings 6902 llb - abec 3 (radial) - 15x28x7

ABEC 3: A standard value used to measure the tolerance of the surface 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 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 little further by machining a recess in 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 lips of seals, razor-thin, that slide 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.

Designed for hub use, this bearing can also serve as a pivot bearing, with the MAX variant being more suitable for suspension systems. It features a deep-groove design and Grade 10 balls for smooth rotation and durability. The bearing is equipped with LLB seals and filled with 90% waterproof, high-pressure grease, making it resistant to the elements and daily use. Part of our Enduro line, these bearings are made from high-quality steel such as high-carbon chrome steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Designed with deep grooves to accommodate larger balls and double-lip seals in a micro-groove labyrinth, they offer superior protection against dirt, water, and grime. Key specifications: static load capacity of 558 lbf (2.48 kN) and a weight of only 15.7 grams.
