If the counterforce is provided not only by the hollow shaft, but also by the
housing, as shown in fig. 48, the forces used must not exceed the values given
in the following table 16.

If the above values are exceeded, the housing, the hollow­shaft bearings or
other gear components may be irreparably damaged. Before replacing the gear
unit on the machine shaft, always check the bearings for any signs of damage.
When using forcing screws or threaded spindles, the head of the thread pressing
against the driven machine should be rounded and well greased to reduce the risk of
seizing at this point.
