Timken M235145-40000 Tapered Roller Bearing Cone

The Timken M235145-40000 is a precision tapered roller bearing cone (inner ring assembly) with a 6.500-inch bore, engineered to support heavy combined radial and axial loads when paired with the matching Timken M235113 cup to form a complete tapered roller bearing set. This single-cone inner ring, part of the M235100 series in the TS design, uses a stamped steel cage and high-grade bearing steel to deliver reliable shaft positioning and long-term performance in demanding industrial environments. Common applications include industrial gearboxes, conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where precise load distribution matters.
