ENDURO BEARINGS 71803 llb a5 - abec 5 (angular contact) - 17x26x5

Discover the high-performance 71803 LLB angular-contact bearing, designed primarily for bicycle hubs but versatile enough for pivot applications. Featuring an ABEC-5 precision grade with deep-groove raceways and grade 10 balls, this bearing ensures smooth rotation and durability. Its C3 clearance provides extra space for thermal expansion, enhancing longevity. Equipped with LLB seals and filled with high-pressure, waterproof grease, it withstands the rigors of daily cycling and harsh weather conditions. When installed correctly (black seal facing inward) and properly adjusted, the bearing's design allows all balls to engage, distributing force evenly, reducing friction, and extending service life. Available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls, these bearings feature deep groove races to accommodate larger balls and dual-lip labyrinth seals for superior protection against dirt and water. Static load capacity: 308 lbf / 1.37 kN. Weighing only 7.6 grams, they are ideal for demanding cycling applications.
