  • For 10,000 Times max during life of gearhead.
  • At input speed of 1000 rpm.
  • At permissible input speed and Continuous Output Torque.
  • Permissible axial load or permissible radial load is the value that satisfies the reducer life when either a pure radialload or an axial load is applied to the flange face. (When radial load is Lr+R=0mm, and axial load is La=0mm)
