NTN NB15101 Tapered Roller Bearing Cone 1 Inch Bore

The NTN NB15101 is a single cone tapered roller bearing designed for applications requiring support of both radial and thrust loads in one direction. This precision-engineered bearing cone is manufactured from through-hardened alloy steel for exceptional strength and durability.

Key Specifications:

• Bore Size: 1 inch (25.4mm)
• Cone Width: 0.8125 inch (20.638mm)
• Maximum Shaft Fillet Radius: 0.8mm
• Static Load Rating: 54,000 N
• Dynamic Load Rating: 46,500 N
• Operating Temperature Range: -40°F to 248°F (-40°C to 120°C)

Features and Benefits:

• Heat-treated rollers with Austenite layer for increased compressive load capacity and corrosion resistance
• Case carburized steel cage evenly spaces rollers to reduce friction, vibration, and noise
• Straight bore design for easy installation
• Compatible with J Series single row tapered roller bearing cups (sold separately)
• Open design allows for lubrication and adjustment

This bearing cone is ideal for high-load, moderate-speed applications including automotive axle systems, conveyor systems, and heavy-duty industrial equipment in mining, construction, and agriculture. The cone must be paired with a compatible cup (outer ring) to form a complete tapered roller bearing assembly.
