MR 18307 LLB - ABEC-5 Radial Bearing (C3 Clearance) - 18mm x 30mm x 7mm This high-performance ABEC-5 radial bearing features deep-groove race design with Grade 10 balls, ensuring smooth operation and durability. Equipped with dual-lip labyrinth (LLB) seals and filled with high-pressure waterproof grease, it is built to withstand the daily demands of cycling in harsh conditions. Ideal for use as a hub bearing, bottom bracket bearing for older square taper cranksets, or as a pivot bearing—though the MAX-type version is better suited for suspension systems. Commonly replacing 6903 bearings in front hubs from brands like DT Swiss, Giant, and Bontrager, with a slightly larger inner diameter of 1mm. Part of the Enduro line, 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 for superior labyrinth protection, ensuring long-lasting performance and resistance to the elements.
