The SKF 6205-2Z double metal shielded deep groove ball bearing provides dependable shaft support for rotating machinery with a 25mm bore requirement. Its standard dimensions of 25 x 52 x 15mm make it suitable for equipment designed around the widely used 6205 bearing size. The single row deep groove raceways accommodate substantial radial loads alongside axial forces acting in either direction, within the bearing's rated limits. SKF catalogue data specifies a basic dynamic load rating of 14.8kN and a basic static load rating of 7.8kN, providing useful reference values for load assessment and bearing-life calculations. Compared with the smaller 6005 series, the 6205 has a larger radial cross-section, while remaining more compact than the heavier 6305 series.
The 2Z suffix identifies a metal shield on each side, rather than contacting rubber seals. These non-contact shields help retain the factory-applied grease and provide protection against larger airborne particles while avoiding the additional running friction associated with contact sealing. This makes the bearing attractive for electric motors, ventilation equipment and relatively clean industrial drive systems. SKF specifies a 14,000rpm limiting speed, with a reference speed of 28,000rpm; these figures are different ratings and should not be treated as interchangeable operating limits. The bearing uses normal (CN) radial internal clearance and a sheet metal cage. For applications involving water, fine dust or heavy contamination, a contact-sealed alternative may be more suitable. Always check the full designation, installation fits and operating conditions when selecting a replacement.
