Federal Mogul NP123221 National Tapered Roller Bearing Cone Bearings & Seals

The Federal Mogul NP123221 is a precision-engineered tapered roller bearing cone manufactured under the National brand. This bearing cone is designed to work in conjunction with a matching cup to create a complete tapered roller bearing assembly, providing reliable load support in applications requiring both radial and thrust load capacity.

Key Features:

• Precision-ground raceways for smooth operation and extended service life
• High-quality steel construction for durability and strength
• Engineered to handle combined radial and axial loads
• Designed to operate with corresponding bearing cup for complete assembly
• Suitable for automotive, industrial, and heavy-duty applications

National tapered roller bearings are known for their quality manufacturing standards and are widely used in wheel hubs, transmissions, differentials, and other rotating applications where precise load distribution is critical. This cone component must be paired with the appropriate cup to form a functional bearing set.
