RH Precision Reduction Gearhead

Nabtesco RH Reducer
The Nabtesco RH Series gearhead is a high-precision hollow shaft gearhead that provides extreme precision and high performance in a compact, ready-to-mount package. The hollow shaft allows for routing of cables, pipe, or hoses through the body of the reduction gear. This is a big advantage for applications where space is at a premium. This series features less than 1 arc-min of backlash and delivers high torsional rigidity. It has a slim profile, integrated base flange, and compatible fittings with all major servo motors. The RH gear reducer is pre-greased and completely sealed for shipping.
