Generally; the shaft is supported by two bearings in the radial direction and the axial direction; at this moment; the bearing on one side is called a fixed side bearing; it accepts both radial and axial loads; between the fixed shaft and the bearing housing The effect of the relative axial displacement. The other side is called the free side; only the radial load is accepted; the axial direction can be relatively moved; to deal with the elastic part of the shaft and the distance error of the bearing of the device due to the temperature change. .
For fixed-side bearings; it is necessary to select bearings that can be moved in the axial direction (such as cylindrical roller bearings) or moved on the mounting surface (such as radial ball bearings). On the shorter shaft; the fixed side and the free side are not In other cases; use only one-way fixed axial displacement bearings (such as radial thrust ball bearings).
