Miniature Actuators

Our miniature speed reducer line includes a wide selection of DC, AC and brushless actuators. You will find complete mini and supermini versions in multiple configurations and three ratios. They provide a reliable, cost-effective and user-friendly solution when space is limited and precision is crucial.

Examples of Mini Actuator Applications Include:

  • Robotics: These devices are a core component of many robotics systems used in modern manufacturing.
  • Consumer electronics: A miniature actuator helps to operate disk drives and perform other essential functions in computers.
  • Prototyping: Mini actuators are the ideal size for smaller manufacturing models and prototypes.
  • Drill presses: Small actuators can provide more precision when adjusting drill press tables for woodworking, metalworking or plastic drilling.
