Different P-Actuators
The series P actuators are based on stack type actuators
covered with stainless steel housing. The top and bottom
plates are epoxied and eliminate technical play. The P se-

ries actuators are not preloaded. Therefore they can’t withstand tensile force and should not be driven dynamically. But
they are able to withstand pressure forces.

of their ability to generate large forces. Also they can be
subjected to high mass loading.

The PA series actuators are based on stack type actuators
using multilayer technology. They are particularly useful for
machine tools and dynamic scanning systems because
