FAG KJLM710949-C Tapered Roller Bearing Cone 2.5591" Bore x 3.957" OD

The FAG KJLM710949-C is a single-row tapered roller bearing cone (inner ring assembly) engineered to handle combined radial and axial loads with precision and durability. Manufactured by FAG (a Schaeffler Group brand), this cone is a separable component designed to pair with the compatible JLM710910 cup (outer ring, sold separately) to form a complete tapered roller bearing assembly.

Key Features:

• Bore Diameter: 2.5591 in (2-35/64 in) — cylindrical bore
• Outside Diameter: 3.957 in
• Cone Width: 0.905 in
• Dynamic Load Capacity: 95 kN
• Cage Material: Pressed steel with window design for even roller spacing
• Ring & Roller Material: Alloy steel for high strength and fatigue resistance
• Operating Temperature Range: -40°F to +250°F (-40°C to +120°C)
• Number of Rows: Single row
• Compatible Cup: JLM710910
• Max Shaft Fillet Radius: 0.12 in

FAG tapered roller bearing cones are engineered with optimized roller end face geometry and guidance rib profiles to improve lubricant film formation and minimize friction. The open design allows for in-place lubrication and precise preload adjustment. For maximum service life, the cone and cup should be replaced as a matched set.

Typical applications include industrial gearboxes, axle assemblies, conveyor systems, construction equipment, and heavy-duty powersports and automotive driveline components. This cone is typically mounted in opposing pairs on a shaft to evenly distribute both radial and thrust loads.
