71803 LLB - ABEC-5 Angular Contact Bearing (C3 Clearance) - 17mm x 26mm x 5mm Discover the high-quality 71803 LLB angular contact bearing, primarily designed for bicycle hub axles but also suitable as a pivot bearing. This bearing features ABEC-5 precision and deep-groove raceways with grade 10 balls, ensuring smooth rotation and durability. The C3 clearance provides extra space for thermal expansion, extending its lifespan. Equipped with LLB seals and filled with high-pressure waterproof grease, it withstands daily loads and weather influences. With correct installation (black sealing lip inwards) and proper adjustment, the bearing engages all balls, distributes force over a larger surface, reduces friction, and extends lifespan. Available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls, these bearings offer deep-groove raceways for larger balls and double-lip labyrinth seals for superior protection against dirt and water. Static load 308 lbf / 1.37 kN. Weighing only 7.6 grams, they are ideal for demanding bicycle applications.
