NTN NBA36 BCA Tapered Roller Bearing Set with Cup and Cone

The NTN NBA36 is a BCA tapered roller bearing set designed for light- and medium-duty automotive and powersports applications. Sold as a complete set, it includes both the cup (race) and cone, providing everything needed for a proper OE-style bearing replacement.

This bearing is precision-engineered from high-quality materials through a case carburization process, producing a hard, wear-resistant outer shell combined with a tough, ductile core. The result is a bearing engineered for enhanced durability, reduced noise and vibration, and extended service life compared to through-hardened alternatives.

Specifications:

• Bearing Type: Tapered Roller
• Bore (Inside Diameter): 1.781 in. (45.2 mm)
• Outside Diameter: 3.063 in. (77.8 mm)
• Width: 0.781 in.
• Includes: Cup and Cone
• Construction: Forged steel
• Warranty: 12 months

Key Features:

• Case-carburized rings and rollers for a hard, wear-resistant surface with a tough core
• Up to 40% longer service life compared to through-hardened bearings
• High-capacity design handles radial, axial, and combined loads
• Excellent shock resistance for demanding operating conditions
• Rolling element cages maintain proper spacing to reduce friction and lower operating temperatures
• Application-specific engineering minimizes noise, vibration, and harshness (NVH)
• Forged-steel construction for durability in harsh environments

Common applications include wheel ends, transmissions, differentials, transfer cases, and engines. The NTN NBA36 is also cross-referenced as SET36 and PTA-36.
