ENDURO BEARINGS 61903 llu/llb cn a5 - abec 5 (radial) - 17x30x7

Enhance your bicycle's performance with the high-quality 61903 LLB CN- ABEC-5 radial bearing. Designed primarily for hub applications, this bearing can also serve as a pivot bearing. The MAX-type version offers superior suspension compatibility. Featuring a deep-groove race design, Grade 10 balls, and dual-lip, full-contact LLU seals facing outward, it provides robust protection against dirt, water, and daily wear. The inward-facing lighter-contact LLB seals ensure a 90% fill of high-pressure waterproof grease, ideal for demanding cycling conditions. With CN clearance, this bearing is perfect for looser press-fit bore applications. Constructed from high-performance materials like high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15, our bearings incorporate the deepest groove races to accommodate larger balls and feature dual-lip labyrinth seals for maximum element protection. Static load capacity: 308 lbf / 1.37 kN. Weight: 15g.
