Low-noise gearboxes

Quiet gearboxes for stepper motor and brushless dc motor. Low noise.

In Nanotec’s low-noise gearboxes, the planetary gears and the ring gear of the first stage are made of a high-quality, low-wear plastic with noise-damping characteristics. The helical toothing allows the teeth to mesh gradually which results in a smoother transmission of forces so that vibrations and noise are further reduced. 

The gearboxes come with many different reductions and, thanks to their compact design, are ideal for use in medical devices and building automation systems. 

  • For BLDC and stepper motors
  • One- and two-stage designs
  • Service life: 5,000 h 
  • Standard with keyway
  • Protection class IP54
