The SKF 3310 ANR is a high-performance double row angular contact ball bearing designed for applications that require superior stiffness, high precision, and the accommodation of significant combined (radial and axial) loads. Featuring a nominal contact angle, this configuration provides inherent axial rigidity in both directions, making it ideal for systems where shaft guidance and high moment loads are critical. The double row design offers a compact solution, effectively replacing two single row bearings, simplifying installation while maximizing load support. Manufactured with a standard internal clearance and steel cage, the 3310 ANR ensures consistent, reliable performance under moderate to high operating speeds and varying temperature conditions.
This bearing is engineered for demanding industrial environments, including high-speed pumps, precision gearboxes, large industrial compressors, and machine tool spindles where uptime and operational reliability are paramount. By distributing loads across two rows, the 3310 ANR significantly enhances service life and reduces the risk of premature failure compared to standard deep groove ball bearings under severe axial stress. Choosing the authentic SKF 3310 ANR ensures you receive a product tested to the highest global standards, guaranteeing operational efficiency, reduced vibration, and minimized maintenance interventions for critical machinery.
