The Enduro Radial Bearing MR 18307 LLU/LLB A5 ABEC-5 (CN) HUB is a high-performance 18x30x7mm bearing engineered for durability and smooth operation. Featuring ABEC-5 precision, deep-groove races with Grade 10 balls, and a CN clearance ideal for looser press-fit bores, it’s commonly used as a hub bearing or in some older square taper bottom brackets. Its dual-lip LLU seals face outwards for maximum protection against the elements, while LLB seals face inwards to retain 90% fill Mobil XHP 222 waterproof synthetic grease, ensuring superior longevity and performance even under daily abuse.
