ENDURO BEARINGS 61801 llu/llb cn a5 - abec 5 (radial) - 12x21x5

Designed primarily as a hub bearing for quick-release bicycle hubs, pedals, and as a pivot bearing, the ABEC-5 radial bearing offers reliable performance for demanding cycling conditions. Its deep-groove race design with Grade 10 balls ensures smooth operation, while dual-lip, full-contact LLU seals protect against dirt, water, and debris, making it ideal for daily use and harsh environments. The lighter-contact LLB seals help contain high-pressure waterproof grease, filling 90% of the bearing for optimal lubrication. The CN clearance specification is suitable for looser press-fit bore applications. Part of the Enduro line, these bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD15 with ceramic or stainless steel balls. Engineered with deep groove races to accommodate larger balls, and featuring dual-lip labyrinth seals, they provide superior protection against elements, ensuring long-lasting performance. Static load capacity: 234 lbf / 1.043 kN. Weight: 5.9 g.
