SKF HM212046 Tapered Roller Bearing Cone 2.5" Bore Single Cone

The SKF HM212046 is a single-cone (inner ring assembly) tapered roller bearing from SKF's HM212000 series. Designed for applications requiring simultaneous support of both radial and axial loads, this inch-series cone is commonly used in wheel bearing, axle differential, and transfer case output shaft applications.

The cone pairs with a compatible cup (outer ring, sold separately — see HM212010 or HM212011) to form a complete single-row tapered roller bearing assembly. As is standard for tapered roller bearings, it is typically installed in opposing pairs on a shaft to evenly distribute loads in both directions.

Key Specifications:

• Bore (Inner Diameter): 2.500 in. (63.5 mm)
• Outside Diameter: 4.813 in. (122.238 mm)
• Cone Width: 1.510 in. (38.354 mm)
• Bearing Series: HM212000
• Bore Type: Straight bore, standard tolerance
• Material: Premium alloy steel with stamped steel cage
• Operating Temperature Range: -65°F to +250°F (-54°C to +120°C)
• Compatible Cup Numbers: HM212010, HM212011
• Sold: Individually (cone only; cup sold separately)

Key Features:

• Precision-ground raceways for accurate contact angles that efficiently manage combined radial and axial loads
• Stamped steel cage maintains even roller spacing, reducing friction, vibration, and noise
• Open design allows for in-place lubrication and precise bearing clearance adjustment during installation
• Standard tolerance, straight bore for straightforward shaft fitment
• Manufactured by SKF, one of the world's leading bearing producers

The SKF HM212046 cone is a direct cross-reference to the Timken HM212046 and NTN HM212046. Both the cone and its mating cup should be replaced together to maximize reliability and service life.
