Avoiding Mounting Errors

Piezo actuators may only be loaded axially. The following figures intend to help you to avoid
mounting errors.

Figure 3: Not tightly screwed at both ends and no angles

A: Wrong: Angular error at the tip
B: Right: Axial loading of the actuator
C: Wrong: The actuator is screwed tight at both ends

Figure 4: Ball tips or flexures for decoupling lateral forces and bending forces
