NTN NBA15 Tapered Roller Bearing with Races

The NTN NBA15 is a precision-engineered tapered roller bearing designed for light- and medium-duty automotive and industrial applications. This OE-style replacement bearing is commonly used in transmissions, differentials, wheel end assemblies, engines, and transfer cases.

Key Specifications:

• Bearing Type: Tapered roller bearing
• Bore Diameter: 1.142 inches
• Outside Diameter: 1.980 inches
• Width: 0.580 inches
• Races Included: Yes (cup and cone assembly)

Premium Construction Features:

• Case carburized rings and rollers provide a hard, wear-resistant outer surface with a tough ductile core
• Forged steel construction delivers exceptional toughness and durability for demanding applications
• Precision rolling element cages reduce friction, prevent damage, and lower operational temperatures
• Application-specific engineering minimizes noise, vibration, and harshness (NVH)
• Offers 40 percent longer life compared to through-hardened bearings

This bearing's tapered design provides high capacity for radial, axial, and combined loads, making it ideal for applications requiring reliable performance under stress. The complete assembly includes both the cone and cup for convenient installation.
