15123 Bearing

The 15123 bearing is a heavy-duty tapered roller bearing cone designed for reliable performance in trailer hub assemblies and axle applications. Commonly used on 6,000 lb. to 8,000 lb. trailer axles, this bearing provides dependable load support, smooth wheel rotation, and reduced friction for equipment trailers, dump trailers, gooseneck trailers, and commercial hauling applications. Precision-manufactured for durability and long-lasting service life, the 15123 bearing is typically paired with the 15245 race (cup) to create a complete bearing set for heavy-duty trailer hubs.
