Koganei Rotary Actuators Piston Type RAP Series

Manufacturer: KOGANEI CORPORATION

Features

The rotary actuator piston type for swing motion is designed to offer efficient use of space, making it ideal for various applications in robotics and automation.

  • 360° Swing Angle
    In addition, the new 360° swing angle specification has been added to the series. This provides more flexibility and improves the range of motion for a wider variety of tasks.

  • Compact Sensor Switch
    Furthermore, the 4mm (0.157 in.) compact sensor switch is now mountable for improved convenience. This addition makes it easier to integrate into tight spaces without compromising performance.

  • Wide Variations in Torque and Swing Angles
    Moreover, a wide variation offers four kinds of torque and five kinds of swing angles. This customization allows users to choose the best configuration for their specific application needs.

  • No Backlash or Air Leakage
    Koganei’s own original double-rack method ensures a no-backlash and no-leak construction. As a result, backlash is eliminated by using a rack that is constantly pushed at the end of the swing. Additionally, the separate piston construction prevents interference with backpressure loads, ensuring no air leakage.

  • Space-Efficient Design
    The square-type design emphasizes space efficiency. The trim body design and piping are concentrated in a single plane, making it easy to mount and further enhancing space utilization.

  • Optional Settings for Expanded Applications
    Lastly, optional settings expand the range of rotary actuator applications. This versatility makes it suitable for a variety of automated processes that require precision and flexibility.
