The SKF 6212-2Z double-shielded deep groove ball bearing provides a robust bearing arrangement for industrial shafts requiring a 60mm bore and reliable support under combined loading. Its 62 series construction offers a balance of radial load capacity, rotational efficiency and installation size, making it suitable for machinery with a 110mm bearing housing and 22mm axial seat. The single row deep groove raceways carry predominantly radial loads and accommodate axial forces in either direction within the bearing's rated limits. SKF specifies a basic dynamic load rating of 55.3kN and a basic static load rating of 36kN, providing essential figures for bearing life calculations and evaluating operating loads. The SKF Explorer design and sheet metal cage support dependable performance in correctly aligned, properly fitted rotating assemblies.
The 2Z suffix identifies two non-contact metal shields, one on each side of the bearing. These help retain the factory grease and reduce the entry of larger contaminants without the additional rubbing friction of rubber contact seals. This makes the bearing a useful choice for relatively clean industrial environments where efficient rotation is important, although metal shields provide less protection against moisture and fine contamination than contact seals. SKF lists a 13,000rpm reference speed and a 6,300rpm limiting speed; these are different catalogue parameters and should not be treated as interchangeable operating limits. The standard 6212-2Z has normal (CN) radial internal clearance, unlike the 6212-2Z/C3. Before replacement, confirm the shielding type, internal clearance and mounting fits rather than selecting solely by dimensions.
Typical Applications:
Industrial electric motor shaft assemblies
Centrifugal pumps and circulation equipment
Industrial ventilation fans and blower drives
Conveyor drive shafts and power transmission systems
General-purpose industrial machinery and gearboxes
