NG047XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to handle combined moment loads (18 ft-lbf rated load moment) while supporting radial and axial loads in any direction, eliminating the need for multiple bearing arrangements.
Thin Section Construction: With a consistent 1" cross-section regardless of bore size (4.75"), this design provides maximum load capacity in minimal space, offering excellent stiffness-to-weight ratio.
Endura-kote Plating: Chromium plating provides superior corrosion resistance and reduced friction, extending service life in demanding environments while maintaining precision performance.
Premium Material Selection: Chrome steel rings and balls with brass cage ensure optimal load distribution and reliable operation across the specified temperature range (-30°C to 110°C).
High Load Capacity: Exceptional dynamic moment load rating of 18,306 lbf and static moment load rating of 26,740 lbf ensures reliable performance under heavy operating conditions.
NG047XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring high moment load capacity
- Aerospace Systems: Aircraft control mechanisms, satellite positioning systems, and radar antennas
- Medical Equipment: CT scanners, MRI machines, and surgical robotics where precision and reliability are critical
- Industrial Machinery: Rotary tables, indexing heads, and precision positioning equipment
- Defense Systems: Turret systems, targeting mechanisms, and surveillance equipment
