The SHD-2UH-LW series was designed to be the most compact, lowest weight, hollow shaft precision gear unit available in the market today. Based on the proven reliability of our SHD component sets, this gear unit has zero backlash, exceptional position accuracy and repeatability. The gearhead incorporates a Harmonic Drive® gear component into an aluminum housing. The gearhead also features a high capacity cross roller bearing and a flanged output to mount the moving load without the need for additional support bearings. The ample hollow shaft allows cables, shafts or pipes to pass directly through the axis of rotation.
Key Features

- Large Hollow Input Shaft
- Zero Backlash
- Accuracy <1 arc-min (most sizes)
- Rigid cross roller output bearing
- Light weight - 30% lower weight than Standard SHF Series
Applications
- Robot: Joint Drive, End Effector
- Machine Tool: Tool Changer, 4th and 5th axis
- Mobile Robots: Wheel Drive, Robot Arm
