  • Page 39: Electric Actuators / Slider Type Common Precautions

    7. Electric actuators / Slider type Common precautions 7.1 Design and selection Warning Do not apply a load in excess of the actuator specification. A product should be selected based on the maximum work load and allowable moment. If the product is used outside of the operating specification, eccentric load applied to the guide will become excessive and have adverse effects such as creating play in the guide, reduced accuracy and reduced product life.
  • Page 40 2. When mounting the workpiece or other device to the actuator tighten the fixing screws with adequate torque within the specified torque range Tightening the screws with a higher torque than the maximum may cause malfunction, whilst tightening with a lower torque can cause the displacement of the mounting position or in extreme conditions detaching of the work piece.
