Enduro bearings 6801 llb - abec 3 (radial) - 12x21x5

ABEC 3: A standard value used to measure the tolerance of the surface of ball 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 a standard. At Enduro, the minimum standard is ABEC 3. ABEC 3: Grade 10 steel balls. 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 bit further by machining a notch into 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 razor-thin sealing lips that slide into a notch with light contact. The outer "lip" keeps water and impurities out, while the inner seal retains grease for smooth rotation and long maintenance intervals.

Article number BB6801LLB EAN 185843000452 Brands Enduro Bearing height (mm) 5 Inner diameter bearing (mm) 12 Outer diameter bearing (mm) 21 Type ABEC 3 6801 LLB - ABEC-3 Radial Bearing (C3 Clearance) – 12mm x 21mm x 5mm Designed as a hub bearing for quick releases, pedals, and pivot points, the 6801 LLB radial bearing offers reliable performance under demanding cycling conditions. While the MAX variant is more suitable for suspension systems, this ABEC-3 bearing features deep-groove balls, Grade 10 balls, and dual-lip labyrinth (LLB) seals that resist daily use and weather. It is pre-filled with 90% Mobilux NGLI 2 high-pressure waterproof synthetic grease, ensuring smooth operation and durability. Part of the Enduro line, these bearings are available in high-carbon chrome steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. They are designed with deep-groove cages to accommodate larger balls and dual-lip seals that ride in micro-grooves, providing long-lasting protection against dirt, water, and grime. Static load 234 lbf / 1.04 kN. Weight: 5.6 g.
