ND070AR0 Bearing Product Overview & Core Advantages
The ND070AR0 is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. Featuring a 30° contact angle, this bearing is optimized to support significant axial static load capacity (5990 lbf) in one direction while handling substantial radial loads. Its Endura-kote chromium plating provides enhanced corrosion resistance, making it suitable for demanding environments. Manufactured to ABEC-1 precision tolerance, it delivers consistent operation and is pre-lubricated for immediate use, offering an excellent balance of high load capacity and compact cross-section with a 0.5" width.
