30256

The 30256 Tapered Roller Bearing is an essential component designed for high-performance industrial applications where combined radial and axial loads are prevalent. This single-row metric bearing features a robust construction, typically comprising an inner ring (cone) assembly and an outer ring (cup), which are separable for simplified mounting and maintenance. With standard dimensions of 280 mm inner diameter (d), 500 mm outer diameter (D), and 89 mm total width (T), the 30256 is engineered to handle substantial static and dynamic loads, ensuring reliable operation across demanding machinery, including heavy-duty gearboxes, automotive differentials, and large rolling mills. We source high-grade materials and utilize precision manufacturing to guarantee the exceptional life and rugged durability expected from top-tier bearings.

Our 30256 tapered roller bearing delivers optimal rolling contact to manage extreme forces efficiently. The carefully calculated taper angle allows the bearing to support high axial loads in one direction alongside significant radial loads. This design choice is crucial for machinery requiring rigid shaft guidance and load distribution. Key specifications often include a dynamic load rating (C_r) of approximately 1,480 kN and a static load rating (C_0r) around 2,130 kN (specific values may vary by manufacturer). For best performance, two single-row 30256 bearings are typically mounted in an opposed configuration.
