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.
