NTN NBHM518445 Tapered Roller Bearing Cone 3.5 Inch Bore

The NTN NBHM518445 is a precision-engineered tapered roller bearing cone designed for heavy-duty industrial and automotive applications. This high-quality bearing component features a 3.5-inch bore diameter and is engineered to work with the matching HM518410 cup to form a complete bearing assembly.

Key Features:

• Bore diameter: 3.5 inches (88.9mm)
• Overall width: 1.5625 inches (39.688mm)
• Compatible cup outer diameter: 6.0 inches (152.4mm)
• Stamped steel cage construction for durability
• Precision ground raceways for smooth operation
• High carbon steel construction for strength and reliability

Tapered roller bearings excel in applications requiring support for combined radial and thrust loads. The cone assembly includes the inner ring, tapered rollers, and cage, designed to handle heavy loads at high speeds while maintaining low friction. This bearing is commonly used in trailer axles, heavy trucks, industrial equipment, and other demanding applications where reliability is critical.

Technical Specifications: The HM518445 cone is part of the HM518400 series and is typically mounted in opposing pairs on a shaft. When paired with the HM518410 cup, the complete bearing set weighs approximately 6.2 lbs and provides exceptional load-carrying capacity. Cross-reference numbers include Timken HM518445, SKF HM518445, and Bower HM518445.
