Models

PRD is a rotary fluid feed-through for robot applications and rotary indexing tables with unlimited rotational movement.

Advantages

  • High strength, long life, no maintenance.
  • Hardened steel inner hub for high power-transmission of modern robots.
  • ISO flange pattern for easy mounting to most robot types without additional adapter plates.
  • 2 or 4 fluid feed-throughs (more available on request).
  • Compact dimensions for minimal impact in customer applications.
  • Smooth-running, long-lasting seal ensures low starting and continuous torque.
  • Dirt protection by means of rotary seals.
  • Air supply via axial or radial fitting screw connections.

Designs

PRD rotary feed-through uses a hardened steel inner hub for unlimited rotational movement and high-power transmission.

An ISO flange pattern mounts directly to most robots with no adapter plates needed, while a smooth-running seal keeps torque low and protects internal components from dirt.
