Activates calculation and/or verification of the permissible speed of the bearing. The (kinematic) limiting speed (specified by the bearing manufacturer) is considered; however, the speed of the bearing is limited by the thermally permissible operating speed in most cases. This accounts for the influence of the operating temperature, the lubricant, and the bearing load on the heat balance in the bearing. For SKF bearings, the adjusted reference speed is determined according to SKF; for all other bearings the thermally permissible operating speed is calculated according to DIN 732:2010, as described in the Schaeffler catalog. The reference speed of the bearing according to ISO 15312 must be specified for this calculation.
