7.4 Shaft-Hub Clamping
Since both rotary and linear movements are carried out with linear motors, a type of shaft load attachment
must be selected which can absorb both torques and forces in the longitudinal direction. A friction-locked
connection is created with the aid of a shaft-hub clamping.

7.4.2 Mounting
•
The shaft-hub clamping has to sit inside the bore by at least the clamp lenght (21 mm).
