Timken 552D Type for Title Tapered Roller Bearing Double Cup – 4.875 In. OD x 2.5 In. Cup Width – New

The Timken 552D is a double tapered roller bearing cup designed as the outer race component for TDO (Tapered Double Outer) assemblies. It features an outer diameter of 4.875 inches and a cup width of 2.5 inches, with the dimensional data sourced from Timken published specifications. The 552D pairs with multiple Timken cone part numbers, including 552 (or 552A), 554, 555, 555S, 558, 558A, 558S, 559, and 560, allowing the assembly to be configured for a wide range of shaft diameters within a common housing bore. The double cup is constructed from Timken high alloy bearing steel and is machined to inch series tolerances. As part of a TDO assembly, the 552D is mounted with two single cones in a back to back arrangement, providing combined radial and thrust load capacity along with resistance to overturning moments. The TDO configuration permits the bearing to be installed in fixed positions or to float in the housing bore. Common applications include industrial gearboxes, axle systems, pinion supports, and other power transmission equipment requiring high radial and axial load capability. The cup carries the registered Timken trademark and is supplied in its original Timken tapered roller bearings box marked 552D. Country of origin and packaging condition are as shown in the listing photos. Sold as a standalone replacement cup component without matching cones.
