The S2HI Series Linear Hydraulic Actuator Assembly is a high-frequency, high-dynamic hydraulic actuator widely applied in high-efficiency dynamic actuation, structural fatigue testing, component durability & performance testing, motion simulation and other scenarios. During operation, external drain oil of this series actuator can flow directly back to the oil tank without an auxiliary oil pump for oil evacuation, delivering a highly integrated and high-performance hydraulic solution.
Manufactured by Shenlead Drive Co., Ltd., the S2HI series hydraulic actuator assembly adopts a double-rod design. Its rated load ranges from 2 kN to 20000 kN, stroke ranges from ±25 mm to ±3000 mm, maximum operating speed reaches 4 m/s, and operating frequency exceeds 400 Hz. Customized actuator assemblies are available for special applications to meet clients’ personalized requirements.
