Timken 97900 Tapered Roller Bearing Outer Race

Timken 97900 is a precision single tapered roller bearing cup (outer race) designed for TS bearing assemblies that support high combined radial and axial loads in heavy-duty industrial applications. Manufactured from through-hardened bearing steel, this cup provides accurate roller guidance and even load distribution, contributing to extended service life under demanding operating conditions. Key dimensions include a Cup Outside Diameter of 9.0000 in (228.6 mm) and a Cup Width of 1.5000 in (38.1 mm); it is part of the 97000 Series with design units in inches. Weight is 18.10 lb (8.20 kg), and the component is designed to be paired with Timken cones such as 97450 or 97500D to form complete TS or TDI bearing assemblies, depending on the application. Common applications span rolling mills, mining machinery, industrial gearboxes, paper processing equipment, marine drives, conveyors, and other heavy-duty rotating systems, with use in repairs, retrofit projects, and preventive maintenance to ensure precise shaft positioning and high load capacity.
