| NF400 | Bore diameter 40" in inch series | Standard inch dimension for compatibility with imperial equipment |
| A | Angular contact design | Optimized for combined radial and axial loading |
| R0 | Standard radial internal clearance | Ensures proper fit and thermal expansion management |
NF400AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel rings and balls with brass cage, providing excellent wear resistance and dimensional stability under heavy loads. The Endura-kote chromium plating enhances corrosion protection in demanding environments.
Superior Load Capacity: With a radial dynamic load rating of 12,147 lbf and axial static load rating of 35,580 lbf, this bearing handles significant combined loads while maintaining precision. The 30° contact angle optimizes load distribution between radial and axial directions.
Precision Engineering: Maintains ABEC-1 tolerance class with tight dimensional controls including bore diameter tolerance of -0.0020" to 0" and radial internal clearance of 0.0000-0.0005". This ensures smooth operation and minimal vibration in precision applications.
Temperature Performance: Operating range of -30°C to 110°C with appropriate lubrication, making it suitable for various industrial environments while maintaining dimensional stability.
