NG120AR0 Bearing Product Overview & Core Advantages
The NG120AR0 is a single row angular contact ball bearing designed for high-precision applications requiring exceptional load handling capabilities. Manufactured to ABEC-1 precision standards with inch dimensions (12" bore, 14" OD), this bearing excels in applications demanding combined radial and axial load capacity. Its 30° contact angle provides optimal performance for angular contact applications, while the Endura-kote chromium plating enhances corrosion resistance and durability. The bearing comes pre-lubricated and features open construction for versatile application requirements.
