Features and Benefits

  • Anti-backlash Nuts Installed
    These small screw jacks are equipped with anti-backlash nuts to minimize vertical backlash between the screw and worm gear nut.
  • Manual Operation
    Accomplished with an easy-to-use hand knob.
  • Plastic Cover Safeguards Surface
    The dial indicator is protected by a removable clear plastic cover.
  • Precision and Accuracy
    Their small size allows for precise control of movement, making them ideal for applications requiring accurate positioning, such as optical lens focusing or industrial control systems. This makes them suitable for applications like smartphones, personal care products, medical devices, and even within furniture and cabinetry.
  • Corrosion-Resistant
    Available in stainless steel for protection against corrosion, making them ideal for harsh environments like marine or chemical settings.
  • Standard Models
    Equipped with anodized aluminum shell cap and housing with stainless steel worm and lifting screws.
  • Optional Models
    Available with sealed 316 stainless steel shell cap, housing, worm and lifting screw.
  • Compact Size and Space Savings
    Micro-miniature actuators are significantly smaller than traditional linear actuators, allowing for integration into very compact devices and spaces.
  • Quiet and Durable Operation
    They often operate with minimal noise, making them suitable for environments where quiet operation is desired. Despite their small size, they can be designed for durability and long-term reliability.
  • Consistency
    Micro-actuators can ensure consistent sample volumes and timing in laboratory settings, which is crucial for reliable experimental results.
  • Automation
    They can be readily incorporated into automation processes, improving efficiency and reducing manual labor.
