  • Page 32: Electric Actuators / Slider Type Common Precautions

    7. Electric actuators / Slider type Common precautions 7.1 Design Caution 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 33 7. When mounting the actuator, use all mounting holes. If all mounting holes are not used, it influences specifications. e.g. the amount of displacement of the table increases. 8. Do not allow the table to hit the workpiece in the positioning operation and positioning area. 9.
