NTN NB11590 Steering Knuckle Tapered Roller Bearing Cone 4WD

The NTN NB11590 is a tapered roller bearing cone engineered for use in 4WD front axle steering knuckle assemblies. Designed as a direct OE replacement, this bearing delivers reliable performance in demanding steering and suspension applications where both radial and axial thrust loads must be managed simultaneously.

NTN is one of the world's leading bearing manufacturers, and the NB11590 is manufactured to meet or exceed original equipment specifications. The tapered roller design allows the cone, cup, and rollers to converge at a common apex, providing superior load distribution and long service life even under heavy-duty off-road conditions.

Key Features:

• Tapered roller bearing cone construction for combined radial and thrust load capacity
• Manufactured to OE specifications for precise fit and function
• Case-hardened alloy steel rollers and races for extended fatigue life
• Industry-standard 11590 bearing number with broad cross-reference compatibility
• Sold individually

The NTN NB11590 is a trusted replacement for worn or damaged steering knuckle bearings, helping restore proper steering response and front axle integrity on 4WD trucks and SUVs. Cross-references to Timken 11590, National 11590, and other major bearing brands.
