If the support is provided not only by the hollow shaft, but also by the housing, as
shown in fig. 43, 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.
