NB080AR0 Bearing Product Overview & Core Advantages
The NB080AR0 is a single row angular contact ball bearing engineered for high-performance applications requiring precise motion control. Designed in inch dimensions, this bearing excels at handling combined loads, simultaneously supporting substantial radial loads and unidirectional axial thrust. Its 30° contact angle is optimized for high axial load capacity. The bearing features a chromium plating (Endura-kote) for enhanced corrosion resistance and is pre-lubricated for immediate service. Manufactured to ABEC-1 precision tolerances, it offers reliable operation in demanding industrial environments.

| R0 | Standard radial internal clearance designation |
NB080AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row angular contact design and 30° contact angle provide excellent capabilities for handling combined radial and axial loads, with a static axial load rating of 3260 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight bore and OD tolerances, ensuring smooth, precise rotation and reliable positioning accuracy.
- Durable Construction: Components made from chrome steel (rings and balls) and a brass cage offer high strength, wear resistance, and stable operation at moderate speeds.
- Corrosion Resistance: The Endura-kote chromium plating significantly enhances corrosion protection, extending service life in challenging environments.
- Pre-lubricated: Factory lubricated for immediate installation and initial operation, reducing maintenance requirements.
NB080AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high axial stiffness and precise bearing dimensions in inch units. Common uses include:
- Industrial Machinery: Precision spindles, rotary tables, and positioning systems.
- Aerospace & Defense: Actuators, control surface mechanisms, and rotor systems.
- Medical Equipment: High-accuracy scanning and imaging devices.
- Robotics: Joint and arm articulation requiring high moment load capacity (11380 lbf static load moment).
