ENDURO BEARINGS 61001 llu/llb cn a5 - abec 5 (radial) - 12x28x8

This high-performance radial bearing is commonly used as a hub bearing for quick-release bicycle hubs and can also serve as a pivot bearing. The MAX-type version is better suited for suspension applications. Featuring a deep-groove race design with Grade 10 balls, it includes dual-lip, full-contact LLU seals facing outward to withstand daily wear and environmental elements, and lighter-contact LLB seals inward to contain high-pressure waterproof grease at 90% fill. The CN clearance makes it ideal for looser press-fit bearing bores. Part of the Enduro line, these bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Engineered with deep groove races to accommodate larger balls and dual-lip seals in micro-grooves, they provide superior protection against dirt, water, and debris. Static load capacity is 443 lbf / 1.97 kN, with a weight of 20.85 grams.
