D-Cut Single Shaft

Features:
  • Improved Dynamic Torque (1.2 times torque of our previous model is generated at 300 r/min, on model : KH42JM2-901)
  • Lowered Vibration & Noise Level (by increased stiffness of body construction)
  • Improved Efficiency (1.1 times of our previous model, by high grade materials.)
  • Strong torque and quieter running by a unique tooth profile.
  • Extended applicable range by standardized specification & higher speed.
