NC050AR0 Bearing Product Overview & Core Advantages
The NC050AR0 is a single row angular contact ball bearing designed for precision applications requiring high reliability. Featuring Endura-kote chromium plating for enhanced corrosion resistance, this bearing excels in handling combined radial and axial loads simultaneously due to its 30° contact angle. With an ABEC-1 precision class and optimized internal geometry, it delivers consistent performance in demanding industrial environments while maintaining compact dimensions (5" bore × 5.75" OD × 0.375" width).
