MOOG servo cylinders<\/strong> are high-performance electrohydraulic actuators designed for applications requiring precise control of position, speed and force<\/strong>.<\/p>\n\n\n\n

Compared with a conventional hydraulic cylinder, a servo cylinder integrates feedback systems and, depending on the configuration, can be combined with dedicated servo valves or proportional valves. The result is a compact, precise actuation system capable of high dynamic performance.<\/p>\n\n\n\n

MOOG develops servo actuators for industrial applications, testing systems, simulation and motion control, with different configurations depending on system characteristics and required performance.<\/p>\n\n\n\n

<\/div>\n\n\n\n

How a MOOG Servo Cylinder Is Configured<\/h3>\n\n\n\n

Depending on the application, a servo cylinder may include:<\/p>\n\n\n\n

    \n
  • a hydraulic cylinder<\/strong> designed for high dynamic performance;<\/li>\n\n\n\n
  • a servo valve or proportional valve<\/strong> installed on the actuator assembly;<\/li>\n\n\n\n
  • an integrated position sensor<\/strong> for continuous monitoring of the piston rod position;<\/li>\n\n\n\n
  • feedback systems and load cells<\/strong> in configurations designed for testing applications;<\/li>\n\n\n\n
  • manifolds and hydraulic connections specifically designed for the application.<\/li>\n<\/ul>\n\n\n\n

    This level of integration allows highly accurate control of actuator movement and enables its performance to be adapted to the required operating conditions.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    Main Types of MOOG Servo Actuators<\/h3>\n\n\n\n

    The MOOG range includes different configurations of hydraulic servo actuators, including:<\/p>\n\n\n\n

      \n
    • Single-Ended Test Servo Actuators<\/strong>, designed for structural testing, fatigue testing and industrial applications;<\/li>\n\n\n\n
    • Double-Ended Test Servo Actuators<\/strong>, suitable for dynamic applications and multi-axis testing systems;<\/li>\n\n\n\n
    • Low-Force Servo Actuators<\/strong>, for applications requiring low forces and high precision;<\/li>\n\n\n\n
    • Hydrostatic Bearing Test Actuators<\/strong>, designed for high-dynamic applications with reduced friction;<\/li>\n\n\n\n
    • special and custom configurations<\/strong>, developed according to specific force, stroke and control requirements.<\/li>\n<\/ul>\n\n\n\n

      MOOG servo cylinders are used in a wide range of applications, including test benches and fatigue testing, structural and automotive testing, simulation systems, presses, steel industry applications, material handling and special motion control systems<\/strong>.<\/p>\n\n\n\n

      <\/div>\n\n\n\n

      MOOG Servo Cylinder Overhaul<\/h2>\n\n\n\n

      In this case, CAMI carried out the complete overhaul of a MOOG servo cylinder with a 140 mm bore<\/strong>, working on the mechanical and hydraulic parts of the unit to restore its correct operating conditions.<\/p>\n\n\n\n

      Overhauling a servo cylinder requires particular attention to dimensional tolerances, sliding surfaces, seals and feedback systems<\/strong>, all of which are essential to ensure accurate and reliable operation.<\/p>\n\n\n\n

      1. Cylinder Body Inspection and Restoration<\/h3>\n\n\n\n

      The cylinder body is inspected to assess its condition and identify any signs of wear or dimensional irregularities.<\/p>\n\n\n\n

      These checks make it possible to determine the work required to restore the correct operating tolerances.<\/p>\n\n\n\n

      2. Piston Rod Restoration<\/h3>\n\n\n\n

      The piston rod is inspected and, when necessary, subjected to restoration and chrome plating<\/strong> to recover the required surface and dimensional characteristics.<\/p>\n\n\n\n

      The quality of the piston rod surface is particularly important to ensure smooth operation and long seal life.<\/p>\n\n\n\n

      3. Piston Rod Reassembly<\/h3>\n\n\n\n

      Following machining and dimensional checks, the piston rod is reinstalled in the cylinder body together with new seals and the components required to restore the unit.<\/p>\n\n\n\n

      Particular attention is paid to smooth movement and correct mating of the mechanical components.<\/p>\n\n\n\n

      4. Position Transducer Installation and Verification<\/h3>\n\n\n\n

      The servo cylinder incorporates a feedback system that continuously detects the position of the piston rod.<\/p>\n\n\n\n

      During the overhaul, the components associated with the position transducer<\/strong> are therefore also checked and reassembled, as they are essential for correct operation of the control system.<\/p>\n\n\n\n

      5. Servo Valve, Reassembly and Final Testing<\/h3>\n\n\n\n

      The assembly may be equipped with a MOOG servo valve dedicated to controlling cylinder movement.<\/p>\n\n\n\n

      CAMI works directly on the mechanical and hydraulic parts of the servo cylinder, while servo valve overhaul activities are managed through MOOG<\/strong>.<\/p>\n\n\n\n

      Once all work has been completed, the unit is fully reassembled and subjected to the required final checks before being returned to the customer.<\/p>\n\n\n\n

      <\/div>\n\n\n\n

      CAMI Service for MOOG Servo Cylinders<\/h3>\n\n\n\n

      CAMI supplies and overhauls MOOG servo cylinders<\/strong>, working on the mechanical and hydraulic components of the actuator and supporting customers in the management of the complete assembly.<\/p>\n\n\n\n

      The experience gained with these components enables CAMI to work on units used both in industrial applications and in systems designed for test benches, simulation and high-performance motion control.<\/p>\n\n\n\n
