Fixture for mounting the rotor:
The fixture must be heat-resistant up to at least +150°C; it must also be
able to support the weight of both the rotor and spindle. In addition, it
must be made of non-ferromagnetic material and the rotor or spindle
must create a level and horizontal surface for the rotor. An example for
such a design is shown below.

Manually operated oil pump and accessories:
Oil pressure: 1500 bar with safety valve; connection winding of the high-
pressure hose: M4x0.5 or M6 (depending on the rotor type)
Oil pumps and accessories can usually be obtained from the
manufacturers of roller bearings.
Clamping device for spindle-rotor attachment:
If the spindle is deformed once the rotor with the step interference fit has
been fitted by shrinking, then a clamping device, among other things, is
needed to correct this deformation. This device must firmly hold the rotor
in place on the spindle and prevent any axial movement of the rotor. Fig.
11-14 illustrates an example.
Arresting device:
When removing the rotor with the step interference fit from the spindle, it
can suddenly slide off of the spindle. The spindle must therefore be
equipped with an arresting device. Fig. 11-16 illustrates an example. The
dimensions of the arresting device must be noted (see Fig. 11-17).
