SHF Gearhead - Standard Series and New Lightweight Series!

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. A New lightweight version is now available which provides the same output torque with a mass averaging 20% lower than the standard series!
