The SKF 3311AC3 is a high-quality genuine double row angular contact ball bearing designed for applications requiring high rigidity and the ability to accommodate combined radial and axial loads. Featuring a 55 mm bore diameter, 120 mm outer diameter, and 49.2 mm width, this bearing offers a C3 internal clearance, indicating a greater than normal radial clearance for specific operating conditions, often involving thermal expansion or misalignment. With a basic dynamic load rating of 102 kN and a static load rating of 71 kN, it ensures reliable performance and extended service life. Its robust design supports high rotational speeds, making it suitable for demanding industrial machinery.
