NA080AR0 Bearing Product Overview & Core Advantages
The NA080AR0 is a single row angular contact ball bearing engineered for precision applications requiring high load capacity and dimensional stability. Featuring inch series measurements with an 8" bore, this bearing is designed to accommodate combined radial and axial loads simultaneously. Its Endura-kote chromium plating provides superior corrosion resistance, while the ABEC-1 precision class ensures reliable performance in demanding industrial environments. The optimized 30° contact angle delivers exceptional axial load handling capability, making it ideal for applications where space constraints and high reliability are critical factors.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|

| A | Angular contact design with 30° contact angle |
| R0 | Radial internal clearance specification (0.0000 – 0.0005") |
NA080AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel for both rings and balls, combined with a brass cage, this bearing delivers exceptional durability and wear resistance. The chromium plating enhances corrosion protection in harsh operating environments.
High Load Capacity: With a radial dynamic load rating of 890 lbf and axial static load rating of 2280 lbf, this bearing efficiently handles significant combined loads. The 30° contact angle optimizes axial load distribution while maintaining radial load capability.
Precision Engineering: The ABEC-1 tolerance class ensures consistent performance with tight dimensional control. The minimal radial internal clearance (0.0000 – 0.0005") provides precise rotational accuracy and reduced vibration.
Wide Temperature Range: Operating temperature range of -30°C to 110°C with factory lubrication makes this bearing suitable for various industrial applications without performance degradation.
