Coaxial servo gear reducers

Coaxial servo gear reducers

SR Series

Product Category

Motion control


Type MR


  • Wide range of servo gearboxes, designed to fit almost all servo motors found on the market
  • Designed for the highest torsional stiffness and the lowest angular backlash, for the maximum torque and overhung loads
  • Bush with slots and hub clamp for servomotor coupling



  • Enhanced dimensional compactness due to direct servomotor coupling
  • Widest range of possible servomotors coupling dimensions.
  • The correct technical solution thanks to a comprehensive range of sizes, gear stages, transmission ratios, designs and non-standard designs.
