The SKF 6022-2Z shielded deep groove ball bearing provides a compact radial cross-section for machinery requiring a substantial 110mm shaft bore. Its 170mm outside diameter and 28mm width make it considerably slimmer than the corresponding 6222 and 6322 series bearings, an important advantage where housing dimensions are restricted. The single row deep groove design carries predominantly radial loads while accommodating axial forces in either direction within its rated limits. SKF specifies a basic dynamic load rating of 85.2kN and a basic static load rating of 73.5kN, providing essential figures for bearing life and loading calculations. Its SKF Explorer design is suitable for applications where operating efficiency, controlled vibration and dependable rotational support are important.
The 2Z designation identifies steel shields on both sides, rather than the contacting rubber seals used in 2RS1 variants. The shields help retain factory-applied grease and protect against larger airborne particles while maintaining a small running clearance, making them appropriate for relatively clean industrial environments. They are not intended to provide the same protection against water or fine contamination as contact seals. SKF lists a 4,000rpm limiting speed and an 8,000rpm reference speed; these are different calculation parameters and should not be treated as interchangeable operating limits. The bearing has normal (CN) radial internal clearance, unlike the 6022-2Z/C3 version, which offers increased internal clearance. Confirm the shaft fits, housing tolerances and complete designation before installation, particularly where operating temperature or interference fits may alter running clearance.
Typical Applications:
Large industrial electric motors and generators
Industrial gearboxes and mechanical transmissions
Conveyor drive shaft and pulley assemblies
Industrial fans and ventilation machinery
Rotating equipment with 110mm shaft bearing seats
