NF040XP0 Bearing Product Overview & Core Advantages
The NF040XP0 is a high-performance thin section bearing featuring four point contact design, engineered for applications requiring exceptional precision and load capacity. This inch-series bearing delivers superior performance in compact spaces with its 4" bore and 0.75" width. The Endura-kote plating provides enhanced corrosion resistance while maintaining precise dimensional stability. Its unique construction enables simultaneous handling of radial loads, axial loads, and moment loads, making it ideal for demanding motion control applications.
Model Code Detailed Explanation
| Code Segment | Technical Meaning | Performance Benefit |
| NF040 | Bearing series designation with 4" bore diameter | Standardized sizing for easy integration |
| XP0 | Specific variant indicating Endura-kote plating and four point contact design | Enhanced corrosion resistance and optimal load distribution |
| Open (Seal Type) | No seals for maximum speed capability | Suitable for clean environments requiring high rotational speeds |
NF040XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: Enables the bearing to handle combined loads including radial (4665 lbf dynamic), axial (6830 lbf dynamic), and moment loads (8 ft-lbf rated) simultaneously, providing exceptional load carrying capacity in a compact footprint.
Endura-kote Plating: Chromium plating on all bearing surfaces significantly improves corrosion resistance while maintaining the precise bearing dimensions and tolerances required for high-precision applications.
Precision Construction: Manufactured to ABEC-1 tolerance standards with chrome steel rings and brass cage, ensuring smooth operation and reliable performance across the specified temperature range (-30°C to 110°C).
Optimized Geometry: The thin section design (0.75" width) combined with precise shoulder diameters provides excellent space efficiency while maintaining structural integrity under demanding operating conditions.
