Hitachi E456498 Bearing Cup – Heavy-Duty Tapered Roller Outer Race for High-Load Rotating Systems in Construction Machinery
The Hitachi E456498 is a robust tapered roller bearing cup (outer race) with a 9-inch outside diameter, engineered for use in final drives, axle housings, and hub assemblies on Hitachi construction equipment. Designed to pair with a matching tapered cone, this bearing cup supports high radial and axial loads under extreme operating conditions.
Manufactured from hardened bearing-grade steel, the E456498 delivers superior wear resistance, dimensional precision, and durability. Its precision-ground raceway ensures smooth roller contact, optimized load distribution, and long service life even in high-vibration or off-road environments.
This bearing cup is an essential part of a complete tapered roller bearing assembly, ideal for use in excavators, loaders, and heavy machinery operating in demanding construction and mining applications.
Technicians and fleet managers trust the Hitachi E456498 for its OEM-grade fit, high load capacity, and consistent performance in mission-critical rotating systems.
