The spring packaged multilayer piezoelectric actuators is composed of stacked multilayer piezoelectric actuators and a preloaded spring. The maximum size of the stacked multilayer piezoelectric actuators is 10×10×100 mm³, which is formed by bonding multiple small laminated units together. The product offers large displacement, low heat generation, and a lifespan exceeding 10^9 cycles. It is primarily used in specialized applications such as fuel injector valves for internal combustion engines with extremely high loads and drive units for fast tool servo systems in industrial machine tools.
