Mounting Guidelines
Piezo actuators must be handled with care because the internal ceramic materials are fragile.1. Piezo stack actuators must only be stressed axially. Tilting and shearing forces must be avoided (by use of ball tips, flexible tips, etc.) because they will damage the actuators.
2. PZTs without internal preload are sensitive to pulling forces. An external preload is recommended for applications requiring strong pulling forces (dynamic operation, heavy loads, etc.).
3. Maximum allowable torque for the top piece can be found in the technical data tables for all Piezo stacks and must not be exceeded. Proper use of wrench flats to apply a counter torque to the top piece when a mating piece is installed will protect the ceramics from damage.
4. When PZTs are installed between plates a ball tip is recommended to avoid bending and shear forces.
Failure to observe these installation guidelines can result in fracture of the Piezo ceramics.
