400 / 454 CR Series Tapered Roller Bearing - 4.000 in Bore - High Radial & Axial Load Capacity
The 400 / 454 Tapered Roller Bearing assembly is engineered for heavy-duty applications demanding high combined radial and thrust loads. Constructed from case-carburized, high-purity alloy steel, this bearing provides exceptional surface hardness and core toughness, crucial for minimizing wear and maximizing operational lifespan in challenging industrial environments. Its separable design, consisting of the 400 cone (inner ring and roller assembly) and the 454 cup (outer ring), allows for precise axial setting and easier mounting. Featuring optimized roller geometry and raceway finish, this bearing minimizes friction losses and reduces operating temperatures, ensuring reliable performance under continuous, high-stress rotation.
Designed as a direct interchange for major competitor brands (e.g., Timken, SKF) in inch-based machinery, the 400 / 454 is the ideal component for critical drivetrain applications, including heavy industrial gearboxes, construction equipment axles, and large agricultural machinery spindles. Implementing this high-precision bearing significantly extends maintenance intervals, reduces total cost of ownership (TCO), and prevents catastrophic equipment failure due to bearing fatigue. We ensure every 400 / 454 bearing meets stringent quality controls for dimensional accuracy and load rating compliance, providing the reliability required for 24/7 industrial operations.
