Deep Groove Ball Bearings SKF 623

SKF 623 compact deep-groove ball bearing with a 3 mm bore and 10 mm outer diameter for precision engineering applications subject to radial loads.

The SKF 623 deep groove ball bearing is a single-row miniature rolling bearing designed for compact installations. With a bore of 3 mm, an outside diameter of 10 mm and a width of 4 mm, this design primarily withstands radial forces. The inner and outer rings, as well as the rolling elements, are made from standard bearing steel 100Cr6. A sturdy sheet steel cage guides the balls evenly in the deep raceways, which promotes smooth running with low rotational resistance.

In which installation spaces is the 623 deep-groove ball bearing used?

This miniature deep-groove ball bearing is primarily used where precise shaft guidance is required in very confined spaces. Typical applications include precision mechanical drives and compact rotary axes with limited installation space. As the component can accommodate low axial forces in both directions in addition to the radial load, it is suitable for a wide range of bearing applications. The cylindrical outer ring without a flange can be fitted flush into suitable housing bores.

What are the key features of the open design of bearing 623?

As an open rolling bearing, this design has no integrated cover plates or sealing discs. This means there are no friction losses caused by sealing lips, which facilitates smooth start-up. However, the design requires a clean installation environment or external sealing of the housing against dirt and moisture. In addition, the lubricant must be supplied separately and selected to suit the application. The standard radial bearing clearance ensures balanced operating clearance at ambient and operating temperatures.
