FAG KJM511946 Tapered Roller Bearing Single Cone 65x110x28mm

The FAG KJM511946 is a single-cone inner ring assembly for a metric tapered roller bearing, designed to handle combined radial and axial (thrust) loads. Manufactured by FAG — a Schaeffler Group brand recognized globally for precision bearing engineering — this cone pairs with a compatible cup (outer ring, sold separately) to form a complete single-row tapered roller bearing unit.

Tapered roller bearings of this type are among the most widely used in industrial and heavy-equipment applications. The angled raceway geometry allows the bearing to support both radial forces and thrust loads simultaneously, making it well-suited for axle, drivetrain, and steering applications in agricultural, construction, and industrial machinery.
