SKF 607-2Z Metal Shielded Single Row Deep Groove Ball Bearing 7x19x6mm

The SKF 607-2Z shielded miniature deep groove ball bearing is engineered for small rotating mechanisms where low friction and compact dimensions are important. Its 7mm bore, 19mm outside diameter and 6mm width allow installation in lightweight shaft supports without requiring the larger housing of a 627 bearing. The single row deep groove raceways accommodate predominantly radial loads together with moderate axial forces in either direction, subject to the bearing's rated capacity. SKF catalogue data specifies a basic dynamic load rating of 2.34kN and a basic static load rating of 0.95kN. These ratings provide a basis for assessing operational loads and service life in small motors, fans and precision mechanical assemblies.

The 2Z designation indicates steel shields on both sides rather than contacting rubber seals. These shields help retain the factory-applied grease and limit the entry of larger contaminants while maintaining a small clearance from the rotating ring. Compared with a contact-sealed alternative, this arrangement generally produces less sealing friction and is suitable for cleaner operating environments. SKF specifies a limiting speed of 43,000rpm, although continuous operating conditions must also account for load, temperature and lubrication performance. The bearing features normal (CN) radial internal clearance, a sheet metal cage and an approximate mass of 8.4g. For replacement purposes, check whether the original equipment requires the shielded 607-2Z or the more contamination-resistant 607-2RSH, as the protection and friction characteristics differ.
