Precision Servo Hydraulic Cylinders | Low-Friction, High-Stiffness

Tianjin Uranus Hydraulic Machinery Co., Ltd. offers a comprehensive range of servo hydraulic cylinders designed for high-frequency, high-dynamic applications that demand the utmost in performance and precision. Our cylinders are optimized for applications such as vibration testing, fatigue testing, and high-speed materials research, where response times and acceleration rates are critical. To achieve superior dynamic performance, we employ design features such as lightweight rods, optimized porting for high flow, and low-friction seals. Our high-frequency cylinders often utilize hydrostatic bearings that eliminate mechanical contact between the piston and cylinder bore, resulting in virtually zero friction and infinite wear life. These bearings also provide exceptional radial stiffness, enabling the cylinder to withstand significant side loads without affecting performance. The cylinders are manufactured with precision-ground rods and honed bores to ensure smooth motion even at high frequencies. We also offer a range of mounting options, including trunnion, flange, and clevis, to accommodate the mechanical requirements of the system. Our engineering team can also design custom cylinders with integrated accelerometers or other sensors to provide direct feedback for control loops. For the research and development community, our high-frequency servo hydraulic cylinders are a trusted tool for generating accurate, repeatable test data. To discuss your high-dynamic testing or process requirements and how our cylinders can meet them, please contact us to speak with a specialist.
