Timken 752B Precision Tapered Roller Bearing Cup

Description:

The Timken 752-B roller bearing cup is a precision flanged outer race designed for use in TSF (Tapered Single with Flange) tapered roller bearing assemblies. The flanged cup provides accurate axial location and improved seal alignment in through-bored housings while supporting heavy combined radial and axial loads. Commonly used in industrial gearboxes, mining equipment, heavy-duty trailers, construction machinery, and power transmission systems, the Timken 752-B is selected by maintenance teams, OEMs, and system integrators for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to ensure reliable performance and long service life.

Applications:

The Timken 752-B roller bearing cup is engineered for use with compatible Timken cones including the 757, 760, and 762 in TSF bearing assemblies. It is widely used in industrial drives, heavy conveyors, mining machinery, steel processing equipment, wheel-end assemblies, and other rotating equipment requiring high load capacity, precise bearing positioning, and dependable operation under combined radial and thrust loading.
