NA070AR0 Bearing Product Overview & Core Advantages
The NA070AR0 is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. Manufactured to ABEC-1 precision standards, this bearing excels at handling combined loads, simultaneously supporting significant radial loads and thrust loads in one direction due to its specified 30° contact angle. Its thin-section design with a 0.25" width offers a compact and lightweight solution, while the Endura-Kote chromium plating provides superior corrosion resistance, making it ideal for demanding environments.
NA070AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NA070 | Indicates the specific bearing series and size designation. |
| A | Signifies the 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
Note: This is an open bearing (no seals/shields) and comes pre-lubricated.
NA070AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row angular contact design, combined with a brass cage and chrome steel components, provides high rigidity and enables the bearing to support a radial dynamic load rating of 823 lbf and a substantial axial static load rating of 2100 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance, ensuring smooth, quiet operation and high running accuracy for precision machinery.
- Corrosion Resistance & Durability: The Endura-Kote chromium plating on all bearing surfaces offers excellent protection against corrosion, significantly extending service life in harsh or humid operating conditions.
- Optimized for Combined Loads: The 30° contact angle is specifically chosen to efficiently manage applications involving a combination of radial and axial loads.
