NB180XP0 Bearing Product Overview & Core Advantages
The NB180XP0 is a high-performance **thin section bearing** featuring **Endura-Kote chromium plating** for superior corrosion resistance. Engineered as a **Four Point Contact Ball Bearing**, it is designed to handle significant **combined radial and axial loads** simultaneously from any direction. Its **single row construction** with optimized **thin cross-section** provides maximum load capacity within minimal space, making it ideal for applications requiring **high rigidity** and precision in compact designs. Manufactured to **ABEC-1 precision** tolerances, this bearing delivers reliable performance in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NB180XP0 | Thin section bearing with 18" bore diameter | Optimized for large diameter, space-constrained applications |
| Endura-Kote | Chromium plating coating | Enhanced corrosion resistance and durability |
| Open | No seals or shields | Maximum speed capability and custom lubrication options |
| Four Point Contact | Ball-raceway contact geometry | Simultaneous radial and axial load capacity in all directions |
NB180XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique ball-to-raceway contact geometry enables the bearing to support substantial combined loads while maintaining precise operation. This design provides exceptional moment load capacity with dynamic load moment of 17,694 lbf and static load moment of 68,090 lbf.
Thin Section Construction: With a compact cross-section of only 0.3125" width and large 18" bore diameter, this bearing maximizes space utilization while delivering high load capacity (radial dynamic: 2,576 lbf, axial dynamic: 4,520 lbf).
Premium Material Selection: Constructed from chrome steel rings and balls with brass cage material, ensuring dimensional stability and reliable performance under heavy loads and varying temperatures (-30°C to 110°C).
Corrosion Protection: The Endura-Kote chromium plating provides superior surface protection, extending service life in challenging environmental conditions while maintaining ABEC-1 precision tolerances.
