NC200AR0 Bearing Product Overview & Core Advantages
The NC200AR0 is a high-precision Angular Contact Ball Bearing designed for demanding applications requiring exceptional accuracy and reliability. Manufactured to ABEC-1 tolerance standards, this single row bearing excels at handling combined radial and axial loads simultaneously, thanks to its specified 30° contact angle. Its Endura-kote Plated chromium coating provides superior corrosion resistance, while the inch-dimension design ensures a perfect fit for specific machinery requirements. This bearing is engineered for high rigidity and stable performance in precision systems.
NC200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NC200 | Basic bearing series designation with specific inch dimensions (20" bore). |
| A | Indicates Angular Contact design with a 30° contact angle. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
NC200AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides high rigidity and is optimized to support significant combined loads, including a radial dynamic load rating of 2863 lbf and a static load moment of 34720 lbf.
- Precision Engineering: Manufactured to ABEC-1 precision class tolerances with strict control over bore diameter and outside diameter for consistent, high-accuracy performance.
- Durable Material & Construction: Features rings and balls made from Chrome Steel and a Brass cage for strength and operational stability. The Endura-kote Chromium Plating significantly enhances corrosion resistance.
- Pre-lubricated & Ready for Service: Comes pre-lubricated for immediate use, operating effectively within a temperature range of -30°C to 110°C.
