NTN NBA4 Tapered Roller Bearing Bearings & Seals

The NTN NBA4 is a precision-engineered tapered roller bearing manufactured by BCA, a brand owned by NTN, one of the world's leading bearing manufacturers with over a century of experience. This multi-purpose tapered roller bearing is designed for demanding automotive and industrial applications including wheel bearing assemblies and manual transmission countershafts.

Key Features:

• Forged-steel construction provides the toughness and durability required for even the harshest applications
• Application-specific engineering reduces noise, vibration and harshness (NVH)
• Rolling element cages reduce friction by keeping rolling elements spaced correctly, preventing damage and resulting in reduced operational temperatures
• OE style replacement bearing designed for direct-fit installation

This tapered roller bearing is engineered to handle both radial and thrust loads simultaneously, making it ideal for wheel hubs, differentials, and transmission applications. The precision manufacturing ensures optimal performance, extended service life, and reliable operation across a wide range of operating conditions.
