MRA-RTU-2

The MRA-RTU-2 Robot Transfer Unit is a 7th-axis linear actuator designed for precise motion control in industrial automation and robotic applications. It features a steel cart custom matched to the robot model and an extruded aluminum actuator body with T-slots for flexible mounting. The MRA-RTU-2 supports user-defined stroke lengths, high-speed travel, and near-zero backlash for accurate, stable positioning. Built with corrosion-resistant components, it provides long-lasting durability and minimal maintenance in demanding environments.

  • Reliable 7th axis motion for articulated robots.
  • Cart designed for the exact make and model of robot used.
  • User defined Strokes.
  • Mounting flexibility in any orientation.
  • Extruded aluminum actuator body with T-slots for ease of mounting.
  • Easy to adjust belt tensioner.
  • One piece machined and stress proof shafted pulley.
  • Zero backlash belt to pulley design.
  • Corrosion resistant components.
  • Washdown Duty or Water- Resistant Options upon request.
  • Integrated cable management.
  • Suggested for use with the following Robots:
    • Yaskawa GP12
    • Fanuc M10 and M20 series
    • Kuka KR Cybertech series
