NTN NBA1 Tapered Roller Bearing Bearings & Seals

The NTN NBA1 is a precision-engineered tapered roller bearing designed for light- and medium-duty applications across automotive and industrial equipment. This OE-style replacement bearing features forged-steel construction that delivers exceptional toughness and durability for demanding operating conditions.

Key Features:

• Bore diameter: 0.688 inches with outside diameter of 1.570 inches
• Case carburization process creates a hard, wear-resistant outer shell with a tough ductile core
• Excellent shock-resistant properties for reliable performance
• 40 percent longer life compared to through-hardened bearing offerings
• High-capacity design handles radial, axial, and combined loads effectively
• Rolling element cages maintain proper spacing to reduce friction and operational temperatures
• Application-specific engineering minimizes noise, vibration, and harshness (NVH)

Ideal for use in transmissions, engines, differentials, wheel-end assemblies, and transfer cases. The precision manufacturing and quality materials ensure optimal performance and extended service life in automotive, powersports, and industrial applications.
