The SKF 6210-2Z shielded deep groove ball bearing is engineered for applications requiring efficient rotation, substantial radial load capacity and reduced maintenance. Its 50mm bore, 90mm outside diameter and 20mm width make it a standard 6210 series bearing suitable for appropriately dimensioned shafts and housings. SKF specifies a basic dynamic load rating of 37.1kN and a basic static load rating of 23.2kN, providing useful reference values for assessing operating loads and bearing life. The single row deep groove raceway arrangement accommodates radial loads together with axial forces in both directions, within the bearing's rated limits. SKF Explorer construction and a sheet metal cage support dependable operation in electric motors, pumps, industrial fans and mechanical transmission assemblies.
The 2Z designation identifies non-contact metal shields on both sides, rather than rubber contact seals. These shields retain the factory-applied grease and provide protection against larger particles while avoiding the additional friction associated with contacting seal lips. SKF lists a reference speed of 15,000rpm and a limiting speed of 8,000rpm; these are different catalogue parameters and should not be treated as guaranteed continuous operating speeds. The shielded design is particularly appropriate for relatively clean environments where low friction matters more than maximum resistance to water or fine dust. For harsher contamination, the 6210-2RS1 contact-sealed alternative may be preferable. The SKF 6210-2Z has normal (CN) radial internal clearance, so any requirement for C3 clearance should be checked before replacement or installation.
Typical Applications:
Industrial electric motors and drive assemblies
Ventilation fans and air handling equipment
Centrifugal pumps and circulation systems
Conveyor drives and tr
