CH 71801 LLB - Ceramic-Hybrid, ABEC-5, Angular-Contact Bearing (C3 Clearance) - 12mm x 21mm x 5mm

This ABEC-5, ceramic-hybrid bearing boasts deep-groove races made of 52100 High-Carbon Chromium alloy, featuring Grade 5 Silicon-Nitride Ceramic balls. It's equipped with dual-lip labyrinth (LLB) seals to resist external elements and retain 90% fill Mobilux NGLI 2 high-pressure, waterproof synthetic grease. Ceramic balls minimize wear and enhance bearing life by avoiding steel-on-steel contact. Proper installation (black seal in) and adjustment engage all bearing balls, distributing force, reducing friction, and minimizing wear for extended life. Angular-Contact bearings typically serve as hub bearings for quick-release hubs, pedals, and can function as pivot bearings, with MAX-type versions ideal for suspension use. Enduro bearings come in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD15 with ceramic or stainless balls. They're designed with the deepest groove races to accommodate the largest balls and have dual-lip seals riding in a micro-groove for superior protection against elements.
