The bearing clearance can be set automatically according (ISO 5753, 2009) (C2…C5) for deep groove ball bearings, four-point bearings, self-aligning ball bearings, spherical and cylindrical roller bearings.
In addition, there are the settings ‘from database’, ‘own input as operating clearance’ and ‘own input’:
•If ‘From database’ is selected, the minimal and maximal values for the bearing clearance are taken from the bearing database. An error message is shown if the bearing data is not selected from database. It is not necessary to use the clearance from database, also the other options for clearance can be selected.
•Selection ‘user input as operating clearance’ means that no modification to the clearance will be done by the software. No interference fit or temperature is taken into account. This is the recommended setting if you know the clearance you want to consider.
•Selecting ‘user input’ allows entering the clearance of the bearing before mounting. Influence of temperature or interference fits will be considered additionally.
•Selecting ‘user input as range’ allows entering the clearance of the bearing before mounting as a range using the -button. Influence of temperature or interference fits will be considered additionally. The load distribution will be calculated using the clearance according to the setting as minimum, medium or maximum value of the range. The -button in the dialog will use the minimal clearance position for sizing of 'Pdmin' or 'Pamin' and the maximal clearance position for sizing of 'Pdmax' or 'Pamax'.
