Discover the high-performance radial bearing designed for industry-leading bicycle hubs, such as those from Industry Nine. This ABEC-5 bearing features a deep-groove design with 52100 high-carbon chromium alloy races and grade 10 balls for exceptional durability. Equipped with dual-lip, full-contact LLU seals facing outward to resist daily wear and environmental elements, and lighter-contact LLB seals inward to contain high-pressure, waterproof grease like Mobil XHP 222. The CN clearance specification ensures an optimal fit for loose press-fit bearing bores. Part of our Enduro line, these bearings are available in various materials including high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Engineered with the deepest groove races possible, they accommodate larger balls and feature dual-lip seals creating a full labyrinth for superior protection against dirt, water, and debris. With a static load capacity of 565 lbf / 2.51 kN and weighing only 13 grams, these bearings deliver reliable performance for demanding cycling conditions.
