NF065AR0 Bearing Product Overview & Core Advantages
The NF065AR0 is a single row angular contact ball bearing designed for demanding applications requiring high precision and reliability. Engineered in inch dimensions, this bearing excels at handling combined loads, simultaneously supporting significant radial loads and high unidirectional axial loads due to its specific 30° contact angle. Its Endura-kote chromium plating provides superior corrosion resistance, making it suitable for harsh environments. Manufactured to ABEC-1 precision tolerances, it ensures consistent performance and long service life in high-performance machinery.
NF065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |

NF065AR0 Bearing Structural Features & Performance Benefits
High Load Capacity: The single row angular contact design and optimized 30° contact angle enable the bearing to support substantial combined radial and axial loads, with an axial static load rating of 11,220 lbf and a radial dynamic load rating of 4,734 lbf.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and OD tolerance: -0.0010" to 0"), ensuring smooth operation and accurate positioning in precision assemblies.
Durable Construction: Components made from chrome steel (rings and balls) and a brass cage provide excellent strength, wear resistance, and dimensional stability under load.
Corrosion Resistance: The Endura-kote chromium plating significantly enhances surface hardness and provides excellent protection against corrosion, extending bearing life in challenging operating conditions.
Optimized Internal Geometry: The specified radial internal clearance (0.0000 – 0.0005") is optimized for precision applications, minimizing noise and vibration while maintaining operational stability.
