NC250XP0 Bearing Product Overview & Core Advantages
The NC250XP0 is a Four Point Contact Ball Bearing featuring Endura-kote Plated surface treatment. Engineered as a thin section bearing with a compact cross-section, it is designed to simultaneously handle significant combined loads, including radial, axial, and moment loads. Its inch-series dimensions and ABEC-1 precision make it an ideal solution for applications requiring high load capacity in a space-constrained design with reliable performance.
NC250XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NC250XP0 | Manufacturer's specific model designation for this bearing series. |
| Endura-kote | Indicates a specialized Chromium Plating coating that enhances surface hardness and corrosion resistance. |
| Open | Signifies the bearing has no integral seals or shields, allowing for custom lubrication schemes. |
| Four Point Contact | Describes the raceway geometry that enables the bearing to support combined moment loads in addition to radial and axial loads. |
NC250XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The Four Point Contact design and single row construction provide exceptional rigidity and the ability to support high dynamic and static load ratings (Radial Dynamic: 3941 lbf, Axial Dynamic: 7140 lbf). This makes it capable of withstanding significant combined loads and a high load moment (37 ft-lbf).
- Durability and Corrosion Resistance: The Endura-kote chromium plating on the chrome steel rings offers superior protection against wear and corrosion, extending service life in demanding environments.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance (0.0000 – 0.0005"), ensuring consistent performance, smooth operation, and precise rotational accuracy.
- Optimized Design: The brass cage ensures stable ball guidance and is suitable for a wide operating temperature range from -30°C to 110°C.
NC250XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, high-capacity solution. Key industries and equipment include:
- Aerospace Actuation Systems and control surfaces
- Robotics joints and rotary actuators
- Medical Equipment such as CT scanners and surgical robots
- Semiconductor Manufacturing Equipment
- Radar and Satellite Communication positioning systems
