The 5311-ZZ is an angular contact ball bearing from the 53 series, featuring a 55mm bore diameter and metal shields on both sides for protection against contaminants. This double row design provides higher load capacity and rigidity compared to single row configurations.
Angular contact ball bearings are commonly used in applications requiring simultaneous radial and axial load support, such as machine tool spindles, gearboxes, pumps, and automotive wheel hubs. The metal shield enclosure makes this bearing suitable for environments with moderate contamination while allowing for higher operating speeds than sealed designs.
