3. For the vertical positioning (x→0), place thin shims over a large surface area under the
machine feet. The number of shims should be kept as low as possible, i.e. stack as few as
possible. This also prevents the machine being subjected to any stress/distortion. Use the
existing tapped holes for the forcing-off bolts to raise the machine.
The balance state of the shaft (full-key or half-key balancing) and alignment errors primarily
influence the service life of the bearing, especially for high motor speeds or when using
rigid couplings.
4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
the coupling.
5. Fix the machine to the foundation. The choice of fixing elements depends on the foundation
and is the plant operator's responsibility.
