  • Please contact SMD for 3 stage ratios.
  • For 1000 Times max during life of gearhead.
  • For input speeds above 3000 rpm, please consult us and provide application details.
  • At permissible input speed and Nominal Output Torque.
  • Permissible axial load or permissible radial load is the value that satisfies the reducer life when either a pureradial load or an axial load is applied to the flange face. (When radial load is Lr+R=0mm, and axial load is La=0mm)
  • Six Times of Safety factor.
