NF047XP0 Bearing Product Overview & Core Advantages
The NF047XP0 is a Four Point Contact Ball Bearing designed for exceptional performance in inch-system applications. This thin section bearing features a single row construction with an open design and a durable Endura-kote chromium plating. Its primary advantage lies in its ability to simultaneously support high combined loads, including significant radial, axial, and moment loads, making it an ideal precision bearing for compact, high-rigidity applications requiring reliable operation.

| XP | Indicates Four Point Contact ball raceway geometry |
| 0 | Specific internal design variant |
NF047XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry enables a single bearing to handle combined radial and axial loads as well as high load moments efficiently, simplifying assembly and saving space.
- High Load Capacity: With a dynamic load moment rating of 10,416 lbf and a static load moment of 17,070 lbf, it provides robust support in demanding applications.
- Thin Section & Precision: The cross-section is compact (Width: 0.75") while maintaining ABEC-1 precision class and a tight radial internal clearance for smooth, accurate operation.
- Durable Construction: Components made from Chrome Steel (rings and balls) and a Brass cage ensure longevity and consistent performance. The Chromium Plating enhances corrosion resistance.
- Wide Operating Range: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, suitable for various industrial environments.
NF047XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and arm linkages requiring high moment load capacity.
- Aerospace: Actuation systems, control surface mechanisms, and radar platforms.
- Semiconductor Manufacturing Equipment: Precision stages and wafer handling robots.
- Medical Equipment: CT scanner gantries and surgical robot arms.
- Industrial Automation: Turntables, indexing tables, and precision gearboxes.
