FAG K6580 Tapered Roller Bearing Cone Inch Series 3.5in Bore

The FAG K6580 is a single-row tapered roller bearing cone (inner ring assembly) manufactured to inch-series dimensional standards. Designed as a direct replacement in demanding industrial and powersports applications, this cone features a 3.500-inch bore diameter and a 2.169-inch cone width, conforming to ANSI/ABMA inch-series tapered roller bearing specifications.

As a separable component, the K6580 cone — comprising the inner ring, tapered rollers, and cage assembly — can be installed independently of its mating cup (outer ring), simplifying mounting and replacement in the field. It is designed to pair with the standard 6535 cup to form a complete tapered roller bearing assembly.

Key Features:

• Bore Diameter: 3.500 in (88.90 mm)
• Cone Width: 2.169 in (55.09 mm)
• Fillet Radius: 0.140 in (3.56 mm)
• Inch-series design per ANSI/ABMA 19 standards
• High-strength bearing steel inner ring, rollers, and steel cage
• Supports combined radial and axial (thrust) loads
• Separable design allows independent mounting of cone and cup
• Compatible with both grease and oil lubrication
• Interchangeable with other manufacturers' 6580 cone designations

The FAG K6580 cone is well-suited for heavy-duty industrial equipment, agricultural machinery, transmissions, and axle applications where high load capacity and precise shaft guidance are required. It is manufactured under the Schaeffler Group's FAG brand, a globally recognized standard in precision rolling bearings.
