Deep Groove Ball Bearings SKF 6207 -Z

The ‘-Z’ designation indicates that the ball bearing is fitted with a single-sided sheet metal cover. This protects the raceway from dust and foreign particles without causing sliding contact or generating frictional heat. The opposite side remains open, allowing lubricant from an oil bath or grease chamber to flow freely into the interior.

The standard radial bearing clearance refers to the standard clearance between the inner ring, the balls and the outer ring when the bearing is in its unassembled state. It compensates for thermal expansion caused by operation and is suitable for standard fit conditions. For applications involving significant heating, it is advisable to check in advance whether a higher bearing clearance class is required.

The permissible operating range is between -20 and +150 degrees Celsius. The combination of 100Cr6 rolling-bearing steel and the heat-resistant sheet steel cage ensures dimensional stability even under thermal stress. The lubricant used should be suitable for this temperature range.

Tolerance class P0 corresponds to the standard tolerance for standard rolling bearings in accordance with international specifications. It defines the permissible dimensional and running errors for the inner and outer rings. This level of accuracy is sufficient for the vast majority of industrial applications in general mechanical engineering and plant construction.

In addition to primary radial forces, this single-row bearing also accommodates axial forces in both directions. Thanks to the deep raceways in the inner and outer rings, the steel balls can transmit moderate axial loads. For applications involving predominantly high axial loads, axial deep-groove ball bearings should be considered as an alternative.
