Timken 762/752-B Tapered Roller Bearing TSF Imperial

Description:

The Timken 762/752-B tapered roller bearing is a precision TSF (Tapered Single with Flange) bearing assembly consisting of the Timken 762 cone and 752-B flanged cup. Designed to support heavy combined radial and axial loads, the flanged cup provides positive axial location and accurate seal alignment in through-bored housings. Commonly installed in industrial gearboxes, mining equipment, rolling mills, heavy-duty trailers, and power transmission systems, this matched bearing assembly is widely used by maintenance teams, OEMs, and system integrators for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to ensure reliable operation and extended bearing life.

Applications:

The Timken 762/752-B TSF bearing assembly is engineered for demanding industrial applications requiring high load capacity, precise shaft positioning, and secure housing location. Its flanged cup design makes it ideal for industrial drives, heavy conveyors, mining machinery, construction equipment, steel processing equipment, and other rotating machinery operating under continuous radial and thrust loading.
