The 61903/29.5 LLB is a specialized ABEC-5 radial bearing, primarily used in Industry-Nine freehubs. It features a unique 29.5mm outer diameter (0.5mm smaller than standard) and a CN clearance specification, making it ideal for looser press-fit bearing bores.
Built with Grade 10 balls and deep-groove races, this bearing is packed with a 90% fill of waterproof high-pressure grease. Double-lip LLB seals provide a full labyrinth defense to protect the internals against daily trail abuse and the elements.
