NA030XP0 Bearing Product Overview & Core Advantages
The NA030XP0 is a thin-section four-point contact ball bearing engineered for applications demanding high precision and space optimization. Featuring a single-row design with Endura-Kote chromium plating, this bearing excels in handling combined radial and axial loads simultaneously from any direction. Its compact cross-section (0.25" width) and ABEC-1 precision make it ideal for high-rigidity support in constrained spaces, while the plated surface enhances corrosion resistance for extended service life.
NA030XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NA030XP0 | Standard thin-section bearing designation | Identifies 3" bore, 3.5" OD configuration |
| Endura-Kote | Chromium plating surface treatment | Enhanced corrosion resistance and durability |
| Four Point Contact | Ball-raceway contact geometry | Superior combined load capacity in all directions |
| Open | No integral seals | Maximum speed capability and custom lubrication options |
NA030XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized ball-raceway geometry enables the bearing to withstand radial loads, axial loads in both directions, and moment loads simultaneously, making it equivalent to a matched pair of angular contact bearings in a more compact envelope.
Thin-Section Construction: With a consistent 0.25" cross-section regardless of bore size, this bearing provides maximum space savings while maintaining high rigidity and precise rotational characteristics.
Premium Material Selection: Chrome steel rings and balls combined with a brass cage ensure dimensional stability, reduced wear, and reliable performance under dynamic loading conditions.
Surface Enhancement: The Endura-Kote chromium plating provides superior corrosion protection, extending service life in challenging environments while maintaining precise bearing dimensions and tolerances.
