NA025AR0 Bearing Product Overview & Core Advantages
The NA025AR0 is a high-performance Angular Contact Ball Bearing designed for inch-system applications requiring exceptional precision and reliability. Engineered with a 30° contact angle and single row construction, it excels at supporting combined radial and axial loads simultaneously. Featuring Endura-kote Chromium Plating for enhanced corrosion resistance and a brass cage for stable operation, this bearing is ideal for high-rigidity, precision applications. Its compact cross-section (0.25" width) and ABEC-1 precision tolerance make it a superior choice for demanding industrial environments.
NA025AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| NA | Angular Contact Bearing Series | Optimized for combined load applications |
| 025 | Bore Diameter: 2.5 inches | Standard inch sizing for compatibility |
| A | 30° Contact Angle | Enhanced axial load capacity and rigidity |
| R0 | Standard Radial Clearance (0.0000-0.0005") | Optimal for precision applications with minimal play |
NA025AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 30° contact angle and single row design provide exceptional stiffness, supporting radial dynamic loads up to 459 lbf and axial static loads up to 1100 lbf. This makes the bearing ideal for applications requiring precise positioning and minimal deflection under combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0006" to 0"), ensuring consistent performance in precision assemblies. The brass cage maintains ball alignment and reduces friction for smooth operation.
Corrosion Resistance & Durability: The Endura-kote Chromium Plating surface treatment provides superior protection against corrosion, extending service life in harsh environments. The bearing operates effectively within a temperature range of -30°C to 110°C and comes pre-lubricated for immediate installation and reliable performance.
