Bearings of the output shaft are arranged as the fixed and floating supports located in bearing housings (table 13.2). The fixed support can take up double-sided axial load. For that the inner and outer rings of the bearing are fixed in both axial directions. The floating support should compensate deformation of the shaft. In this case the inner ring of the bearing is fixed in both directions. For that we use boundary plates (tables 13.3 and 13.4) or spring rings (table 13.5). The outer ring is left free.
