ENDURO BEARINGS Ch 71801 llb - ceramic hybrid (angular contact) - 12x21x5

Discover the high-performance capabilities of the CH 71801 LLB ceramic-hybrid angular-contact bearing, designed for demanding cycling applications. Featuring deep-groove design with 52100 high-carbon chromium alloy races and Grade 5 silicon-nitride ceramic balls, this bearing offers exceptional durability and reduced wear. Equipped with dual-lip labyrinth (LLB) seals to resist external elements and contain high-pressure synthetic grease, it ensures reliable operation in tough conditions. The Si3N4 ceramic balls eliminate steel-on-steel contact, extending bearing life. Proper installation (black seal facing inward) and adjustment allow all balls to engage, distributing force evenly to reduce friction and wear. Ideal as a hub bearing for quick-release hubs, pedals, or pivot points, though MAX-type versions are better suited for suspension systems. Our Enduro bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls, featuring deep-groove races and dual-lip seals for superior protection against the elements. Static load: 234 lbf / 1.04 kN | Weight: 5.31 g
