NF250AR0 Bearing Product Overview & Core Advantages
The NF250AR0 is a high-performance single row angular contact ball bearing designed for demanding applications requiring exceptional precision and reliability. Engineered with an Endura-kote chromium plating, it offers superior corrosion resistance and extended service life. This bearing is optimized to handle significant combined loads, efficiently supporting both radial and axial forces simultaneously due to its specific 30° contact angle. Its inch-series dimensions and ABEC-1 precision class make it an ideal component for compact, high-rigidity assemblies where space and performance are critical.
NF250AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NF250 | Bearing series and size designation (25" bore, 26.5" OD). |
| A | Signifies Angular Contact design with a 30° contact angle. |
| R0 | Indicates standard radial internal clearance (0.0000 – 0.0005"). |
NF250AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a brass cage, provides stable operation and high rigidity. It is rated for a dynamic radial load of 9585 lbf and a static radial load of 34700 lbf, enabling it to handle significant combined loads.
- Precision Performance: Manufactured to ABEC-1 tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring smooth and precise rotation in high-accuracy applications.
- Durability & Corrosion Resistance: The Endura-kote chromium plating on the chrome steel rings provides excellent protection against corrosion, significantly enhancing the bearing's lifespan in harsh environments.
- Optimized for Combined Loads: The 30° contact angle is specifically engineered to support substantial axial loads (26100 lbf static axial) in addition to radial loads, making it suitable for complex load scenarios.
NF250AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust performance and corrosion resistance, including:
- Aerospace Actuation Systems
- Heavy-Duty Industrial Machinery and gearboxes
- Marine Equipment and deck machinery
- Construction Equipment pivot points and rollers
- Precision Rotary Tables and indexing heads
