Reliability of the piezo-actuators deployed in SRF cavity tuners operated at high dynamic voltage range rate conditions can lead to a significant impact on the overall performance of the SRF linacs. We tested at FNAL piezoactuators P-844K075 that were developed at Physik Instrumente (PI) for LCLSII project. Although these actuators were developed for a CW linac we tested them at high dynamic rate inside a cryogenic/insulated vacuum environment. Results of the tests will be presented. Different modes of the piezo-actuators failure will be discussed.
