Deep Groove Ball Bearings SKF 625

The bearing is used in industrial applications where space is limited, for example in small drives, precision mechanical units or metrological instruments. It primarily absorbs radial loads, but thanks to its deep raceways, it also guides the shaft stably in both directions even when subjected to slight axial forces.

As there are no fixed cover plates or sealing washers, friction losses are minimal, meaning the bearing rotates particularly smoothly. However, contaminants can reach the raceways more easily, which is why the bearing housing should be protected against dirt and supplied with lubricant via an external source.

The designation P0 or ABEC 1 describes the standardised tolerance class for rolling bearings. It defines the permissible dimensional, form and running deviations for rings and rolling elements. For the majority of industrial applications in general mechanical engineering and equipment manufacturing, this standard tolerance provides sufficient fitting accuracy.

The specified operating temperature range is from -20 to +120 degrees Celsius. Within this range, the 100Cr6 rolling bearing steel and the sheet steel cage retain their dimensional stability. When designing the system, the selected lubricant should be suitable for the same temperature range.

Standard radial bearing clearance refers to the factory-set standard clearance between the inner ring, the balls and the outer ring when the bearing is unmounted. This clearance compensates for the usual reduction in clearance that occurs when the bearing is pressed onto the shaft and is sufficient at normal operating temperatures to prevent the rolling elements from seizing.
