Timken 14276 D Tapered Roller Bearing Cup – 73.025 mm OD (2.875 in) – Premium Outer Ring

The 14276 D is the essential outer ring (cup) component designed for use with the 14276 cone in standardized tapered roller bearing assemblies. Engineered by Timken, this cup is manufactured from high-grade, case-carburized steel, providing superior surface hardness and exceptional core toughness necessary to withstand the high stress characteristic of combined heavy radial and axial loads. Its precise geometry ensures perfect alignment with the associated cone assembly, minimizing friction and optimizing load distribution across the rollers. This structure is critical for applications in automotive differentials, transmissions, and industrial machinery where reliable, long-term performance under demanding cyclic loading is mandatory. Selecting the Timken 14276 D ensures maximum operational uptime and reduced Total Cost of Ownership (TCO). The cup's rigorous manufacturing tolerances guarantee a precise fit and easier installation, reducing the risk of premature failure often associated with improperly seated bearings. Furthermore, its optimized internal design facilitates efficient lubricant flow, extending the service life of both the cup and cone components. This bearing cup is the robust solution for engineers seeking unparalleled reliability and maximum durability in critical rotating applications, maintaining stringent standards required across agricultural, construction, and general heavy industry.
