The Bower 52400 bearing cone is a tapered roller bearing component designed to support radial and axial loads on shafts while reducing friction between moving components in industrial rotating equipment. This inner ring fits with the corresponding bearing cup and rollers, and is made from hardened bearing steel with a press-fit mounting on the shaft as part of the bearing assembly. It is widely used in industrial pumps, compressors, conveyors, gear reducers, electric motors, and other rotating machinery that rely on tapered roller bearings to handle combined radial and thrust loads under heavy-duty operating conditions. Common replacements include the Bower 52400XP, Timken 52400 series cone, and SKF 52400 tapered cone.
