FAG KM88046 Tapered Roller Bearing Cone Single Row Inch Series

The FAG KM88046 is a single-row tapered roller bearing cone (inner ring assembly) manufactured by FAG, a Schaeffler Group brand. This cone is the separable inner component of a complete tapered roller bearing, consisting of the inner ring, tapered rollers, and roller cage assembled as one unit.

Designed for use in the inch-series M88046 bearing family, this cone pairs with a compatible cup (outer ring) to form a complete tapered roller bearing assembly. The matching cup cross-reference is M88010. Together, these components make up the FAG KM88046-M88010-XL assembly.

Key Specifications:

• Bore Diameter (ID): 31.75 mm (1.250 in)
• Assembly Outside Diameter: 68.262 mm (2.688 in)
• Assembly Width: 22.225 mm (0.875 in)
• Dynamic Load Rating (Cr): 67,000 N
• Static Load Rating (C0r): 72,000 N
• Limiting Speed: 10,700 RPM
• Inch-dimensioned series

Key Features:

• Separable cone design allows independent mounting and replacement of inner and outer components
• Conical raceways and tapered rollers support combined radial and axial (thrust) loads in one direction
• Geometric precision minimizes sliding motion between rollers and raceways, reducing wear
• Axial clearance (end play) or preload is adjustable during assembly by moving components axially
• Manufactured to FAG quality standards as part of the Schaeffler Group product portfolio

The FAG KM88046 cone is suitable for a wide range of industrial and powersports applications where precise shaft guidance and high load capacity are required. For optimal bearing performance and service life, it is recommended to replace the cone and cup simultaneously using components from the same manufacturer.
