NA075XP0 Bearing Product Overview & Core Advantages
The NA075XP0 is a Four Point Contact Ball Bearing engineered for high-performance applications requiring exceptional moment load capacity. This thin section bearing features a single row design with a Chromium Plated surface (Endura-kote), offering superior corrosion resistance and extended service life. Its primary advantage lies in its ability to simultaneously support combined loads—significant radial, axial, and moment loads—within an extremely compact cross-section (0.25" width), making it ideal for space-constrained, high-precision machinery.
NA075XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NA075 | Bore diameter designation (7.5 inches) |
| XP0 | Specific series designation for this thin-section, four-point contact bearing configuration. |
Key Feature Highlights: The "Four Point Contact" design is integral to the bearing's identity, enabling it to handle complex load combinations. The Endura-kote Plating provides a hard, durable, and corrosion-resistant surface.
NA075XP0 Bearing Structural Features & Performance Benefits
- High Moment Load Capacity: The unique four point contact raceway design allows a single bearing to support substantial dynamic load moments (3165 lbf) and static load moments (9120 lbf), effectively replacing more complex bearing arrangements.
- Compact & Lightweight Design: With a thin 0.25" cross-section and a weight of only 0.34 lbs, it minimizes system weight and envelope size without compromising performance.
- Enhanced Durability & Corrosion Resistance: The Chromium Plating on the rings significantly improves wear resistance and protects against corrosion, suitable for a temperature range of -30°C to 110°C.
- Precision & Reliability: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, ensuring consistent performance and smooth operation.
- Robust Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage provide high strength, durability, and stable operation under high loads.
NA075XP0 Bearing Typical Application Areas
This bearing is designed for applications where high moment load capacity is critical within a limited space. Key industries and equipment include:
- Robotics: Robotic arms and rotary joints.
- Aerospace & Defense: Actuators, radar platforms, and gimbal systems.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Medical Equipment: CT scanner gantries and surgical robot joints.
- Industrial Machinery: Rotary tables, indexing heads, and other high-precision rotary applications.
