SKF 6009-2Z Metal Shielded Single Row Deep Groove Ball Bearing 45x75x16mm

The SKF 6009-2Z shielded deep groove ball bearing provides dependable shaft support for industrial machinery requiring a 45mm bore within a 75mm outside diameter. Its 16mm width makes it a compact alternative to the heavier 6209 and 6309 series, provided the application's load requirements are within its rated capacity. The single row deep groove raceways accommodate radial loads together with axial forces acting in either direction. SKF specifies a basic dynamic load rating of 22.1kN and a basic static load rating of 14.6kN. These values help engineers assess bearing life, operating loads and replacement suitability. The bearing's SKF Explorer performance classification and sheet metal cage support applications requiring consistent rotational performance.

The 2Z suffix identifies metal shields on both sides, rather than rubber contact seals. These non-contact shields help retain the factory-applied grease while reducing the entry of larger particles, with minimal additional running friction. They are particularly suitable for relatively clean, enclosed machinery where rotational efficiency matters. However, they do not provide the same protection against fine dust, splashing water or moisture as contact-sealed alternatives. SKF lists a reference speed of 20,000rpm and a limiting speed of 10,000rpm; these are different catalogue parameters and should not be treated as guaranteed operating speeds. The bearing has normal (CN) radial internal clearance, unlike the 6009-2Z/C3 version. Check shaft fits, temperature and the complete bearing designation before installation.

Typical Applications:

Industrial electric motors and drive assemblies

Ventilation fans and air handling equipment
