The element “Roller bearing” defines a connection to the rolling bearing calculation.all_img49

The current shaft can be connected to the inner or to the outer ring of a roller bearing. The other ring of the bearing can be connected to either the housing or another shaft.

By clicking on the button “‘Geometry, Material, Temperature, Lubrication’ is connected“ the user is prompted, by means of a pop-up window, to set those flags of the data to be transferred to bearing calculation. Shaft diameters, material data, lubrication and temperature data can be transferred to the bearing calculation. Displacements, loads and speeds are always connected.


The shaft is can be supported radially and axially to the left and the right. This setting changes the connection of the bearing outer ring to the shaft/housing. If the bearing cannot constrain a certain movement, there won’t be reaction forces in that direction.

The bearing offsets will move the node of the secondary shaft (or housing) in this direction, it will therefore generate forces to the current shaft in the direction of the offset. The offset can be used to generate bearing pretension in axial direction or to take misalignments of the housing into account.

Using the all_img3-button next to the bearing type a dialog is shown to select a rolling bearing from the database.

If a rolling bearing element is added an entry for the bearing in the system-tree will be added. If this element is selected the dialogs of the rolling bearing calculation are active to define the bearing.
