RR USA Right-angle Gear Reducers by Reggiana-Riduttori

RRUSA Right Angle Gear Reducers with Male Spline

The right-angle gear reducers offer the same power transmission capabilities as the inline versions, but utilize less space by providing power transmission at a 90 degree angle. They accept the same inputs and outputs.

Output shafts include:

  • Male splined
  • Cylindrical keyed (SAE or metric)
  • Hollow-shaft
  • Hex-shaft
  • Integral pinions

Available inputs:

  • Negative brakes
  • Motor connections for hydraulic motors
  • Motor connections for electric motors
  • Male inputs for pulleys
  • Male inputs for chain sprocket transmission
