The 960 Series Servohydraulic Torsional Test Systems are designed for static and fatigue tests of rotary components such as axles, couplings, drive shafts, and universal joints. Each torsional tester is configured to match rotary displacement and torsional load test requirements. We offer seven models of static double vane rotary actuators with 100 degree rotation with ratings from 1,237 Nm (11,000 lbf∙in) up to 78.7 kNm (696 klbf∙in). Each test system includes a rotary actuator, servovalve, hydraulic subsystem including power pack rated to match torque and displacement performance requirements, choice of static Q Series or fatigue based L Series digital servocontroller, torque cell, digital encoder, reaction brackets, anti-thrust bearings, and test table.
