YJ Piezo Ceramic Tube Series
YJ Piezo's premium piezoelectric ceramic tubes (PZT tubes) engineered for precision ultrasonic and actuation applications. YJ Piezo's tubular piezoelectric element series delivers excellent electromechanical coupling (K31: 15.13-21.86%) with tight dimensional tolerances and resonant frequencies from 28 to 149 kHz. These cylindrical piezo elements are ideal for micro-displacement actuators, ultrasonic sensors, sonar systems, and medical diagnostic equipment.
Features & Applications
Primary Applications & Technical Features
- •Micro-Displacement Actuators: Precise radial expansion/contraction for nanopositioning systems, optical alignment, and valve control applications

Precision Machining Capabilities
Our CNC centerless grinding systems achieve wall thickness uniformity of ±0.02mm and concentricity ≤0.03mm. This precision ensures symmetric radial motion and predictable resonance characteristics essential for actuator and sensor applications.
Custom Electrode Patterns
We offer standard full-coverage electrodes plus custom segmented patterns (quadrant, octant) for directional actuation and multi-axis scanning applications. Silver, nickel, and gold electrode materials available.
Material Selection
Material selection depends on sensitivity, loss and drive conditions. PZT-5H, PZT-4 and PZT-8 are candidate material families for engineering review. A Curie temperature is not a continuous operating-temperature rating: confirm the allowable temperature, field, duty cycle, mounting and validation method for the actual tube assembly.
