NG040AR0 Bearing Product Overview & Core Advantages
The NG040AR0 is a single row angular contact ball bearing designed for high-performance applications requiring precision and reliability. Manufactured in inch dimensions with a 4" bore and 6" outside diameter, this bearing excels in handling combined radial and axial loads simultaneously due to its 30° contact angle. The Endura-kote chromium plating provides superior corrosion resistance and extended service life. With an ABEC-1 precision class and optimized internal geometry, it delivers exceptional running accuracy and stability for demanding industrial environments.
