Timken L507949XS Tapered Roller Bearing Assembly

The L507949XS Tapered Roller Bearing Assembly is a single-row tapered roller bearing designed to support combined radial and axial loads in industrial machinery, heavy equipment, and power transmission applications. The assembly uses a precision-machined cone with tapered rollers and a steel cage to deliver high load capacity, reduced friction, and long service life, keeping shaft alignment precise in gearboxes, conveyors, machine tool spindles, wheel hubs, and automotive axles. Specifications include a bore of 57.15 mm (2.250 in), an outside diameter of 87.31 mm (3.4375 in), and an overall width and cone width of 18.26 mm (0.719 in); the bearing is open and built from through-hardened bearing steel, with a dynamic load rating of 62.7 kN and a static load rating of 95.6 kN. Common replacements include Timken L507949/L507910, SKF L507949-series equivalents, and NTN or KOYO equivalents with matching dimensions.
