SKF 6213-2Z Metal Shielded Single Row Deep Groove Ball Bearing 65x120x23mm

The SKF 6213-2Z double shielded deep groove ball bearing is engineered for rotating machinery where reliable radial load support, moderate axial load capacity and efficient running are important. Its 65mm bore, 120mm outside diameter and 23mm width make it a suitable choice for substantial industrial shaft arrangements without requiring the larger housing diameter of a 6313 bearing. The single row deep groove raceways accommodate radial forces and axial loads in either direction within the bearing's operating limits. SKF catalogue data specifies a basic dynamic load rating of 58.5kN and a basic static load rating of 40.5kN, providing useful values for bearing life calculations and mechanical load assessment. Its SKF Explorer classification reflects the manufacturer's optimised bearing design.

The 2Z designation identifies a steel shield on each side of the bearing. These shields form a narrow non-contact gap with the inner ring, helping retain factory-filled grease while protecting against larger particles and debris. Because the shields do not rub against the rotating inner ring, this configuration is particularly attractive for electric motors, fans and other equipment where low friction matters. SKF lists a 6,000rpm limiting speed for the double shielded version. However, metal shields offer less protection against water and fine contamination than rubber contact seals, so operating conditions must be considered carefully. The bearing has normal (CN) radial internal clearance; applications requiring greater initial clearance may call for a C3 variant. Before installation, confirm the shaft and housing tolerances, mounting arrangement and complete bearing designation.

Typical Applications:

Industrial electric motors and drive assemblies
