SHF-2UH

The SHF-2UH series is a compact hollow shaft gearhead which has zero backlash as well as exceptional accuracy and repeatability. The gearhead incorporates a Harmonic Drive® gear component into an integral housing. In addition to the hollow shaft, the gearhead also features a high capacity cross roller bearing and output flange to mount the load without the need for additional support bearings. We also have a high torque version, SHG-2UH as well as a lightweight version, SHF-2UH-LW available.

Key Features:

Zero Backlash
Large Hollow Input Shaft
Accuracy <1 arc-min (most sizes)
High torsional stiffness
Robust cross roller output bearing
Output flange for direct mounting of load
