  • At permissible input speed and Continuous Output Torque
  • At input speed of 1000 rpm
  • Efficiency = 85% at permissible input speed and full load
  • Permissible axial load or permissible radial load is the value that satisfies the reducer life when either a pure radial load or an axial load is applied to the flange face. (When radial load is Lr+R=0mm, and axial load is La=0mm)
