The contacting point must be on the top center surface of actuator.

All the actuator should be preloaded. 2 All actuators are most made by piezoceramic material，It’s better for surface to surface contacting than point to point or line to line contacting. 6 stb S E R A M IC S I n d u str ie v ertr etu n g Stack Working Condition: This piezo stack working temperature range is -20~120℃,but need work in lower humidity condition. If high humidity the insulation result of some components came down and will affect the life time of stack. 7
