ENDURO BEARINGS Ch 6801 llb - ceramic hybrid (radial) - 12x21x5

Enhance your cycling performance with the high-precision ABEC-5 ceramic-hybrid radial bearing. Measuring 12mm x 21mm x 5mm, this bearing features deep-groove races made from high-carbon chromium alloy (52100) and Grade 5 Silicon-Nitride ceramic balls, ensuring durability and smooth operation. Equipped with dual-lip labyrinth (LLB) seals, it offers superior protection against dirt, water, and external elements, while containing high-pressure, waterproof synthetic grease for optimal lubrication. The Si3N4 ceramic balls significantly reduce wear and extend bearing life by eliminating steel-on-steel contact. Ideal as a hub bearing for quick-release hubs, pedals, or as a pivot bearing—though the MAX-type version is better suited for suspension systems. Part of the Enduro line, these bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Engineered with deep-groove races to accommodate larger balls and dual-lip seals that form a micro-groove labyrinth, providing excellent protection against the elements. Static load capacity: 234 lbf / 1.04 kN. Weight: 5.31 g.
