Flexibility that enables small and high-speed displacements using piezoelectric elements! Achieving a compact shape with a minimum inner diameter of 3mm.
The "Precision Bellows" is a small multi-layer bellows with an inner diameter of 3mm, used as a sealing element that displaces with high precision in piezoelectric injector systems. It maintains a seal to keep the piezoelectric element completely dry while enabling minute and rapid displacements through its flexibility. This product is also used in accumulators mounted in hybrid vehicle brake systems, allowing for high braking force even when the motor is stopped. 【Features】 ■ Custom designs available to meet customer requirements ■ Realization of compact shapes (minimum inner diameter of 3mm and above) ■ Production facilities available in clean rooms ■ Mass production capabilities *For more details, please refer to the related link page or feel free to contact us.
