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

ABEC 3: A standard value used to measure the w tolerance of the surface of the roller bearings. There are five classes: 1, 3, 5, 7 and 9. The higher the ABEC class the greater the precision, efficiency and speed capability, but the highest ABEC classes are not necessarily the fastest rotating parts. All quality manufacturers around the world use at least ABEC 1 as standard. At Enduro the minimum standard is ABEC 3. ABEC 3: Steel balls Grade 10. Track in an alloy of chrome 52100 and high-quality 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 little further by machining a notch 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 that rubs against an uneven surface, the LLB type uses 2 lips of seals, fine like a razor blade that slides in a notch with a light contact. The outer «lip» keeps out water and impurities, while the inner seal retains grease for smooth rotation and long intervals between services.

Item Number BB6801LLB EAN 185843000452 Brands Enduro Bearing Outer Diameter (mm) 21 Bearing Inner Diameter (mm) 12 Bearing Height (mm) 5 Type ABEC 3 6801 LLB - ABEC-3 Radial Bearing (C3 Clearance) – 12mm x 21mm x 5mm Designed as a hub bearing for quick release couplings, pedals and pivots, it provides the 6801 LLB radial bearing provides reliable performance under demanding cycling conditions. Although the MAX variant is better suited to suspension systems, this ABEC-3 bearing features deep-groove balls, Grade 10 balls and dual-lip labyrinth (LLB) seals that can withstand daily use and weather. It is pre-filled with 90% Mobilux NGLI 2 high-pressure waterproof synthetic grease, which ensures 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.
