Planetary Gearboxes – Right Angle
Precision Advanced Type
PGRH Series
The PGRH Precision Series right-angle housing, square mounting flange, with caged precision class helical planetary gears, in sizes through 220 mm. High torque capacity, quiet operation and backlash as low as <2 arcmin. The square output flange makes it particularly easy to install and save spaces for a wide range of applications. PGRH series gearhead overall design suitable for combination operation with servo motor high-speed input and achieves maximum torque output. Precision gear design and gear processing create a planetary gearhead with low backlash operation, high efficiency, low noise and long service life performances.
