NF160AR0 Bearing Product Overview & Core Advantages
The NF160AR0 is a high-performance angular contact ball bearing designed for demanding applications requiring exceptional precision and reliability. Engineered in inch dimensions, this single row bearing features a specialized Endura-kote chromium plating for enhanced corrosion resistance. Its primary strength lies in its ability to support high combined loads, efficiently handling significant radial loads and unidirectional axial loads simultaneously, thanks to its defined 30° contact angle. With an ABEC-1 precision class and optimized internal geometry, it delivers smooth operation and high rotational accuracy, making it an ideal solution for high-rigidity mounting arrangements.
NF160AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NF160 | Bearing series and size designation (16" Bore, 17.5" OD) |
| A | Angular Contact design with a 30° contact angle |
| R0 | Standard radial internal clearance |
Key Feature: The model designation confirms this is an open, lubricated, angular contact bearing without seals or shields, intended for applications where external sealing is provided and controlled lubrication is possible.
NF160AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row angular contact design, combined with a brass cage and chrome steel components, provides high dynamic and static load ratings (7563 lbf dynamic, 22480 lbf static radial), enabling stable performance under significant combined loads.
- Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional control on bore, outside diameter, and width, ensuring precise shaft and housing fits for accurate rotational performance.
- Corrosion Resistance & Durability: The Endura-kote chromium plating on all bearing surfaces significantly improves corrosion resistance, extending service life in challenging environments.
- Optimized Internal Geometry: The specified radial internal clearance and 30° contact angle are engineered to provide optimal preload and stiffness characteristics in the final application.
