What is a planetary gear? A planetary gear (or planetary gearbox) is a gearbox with the input shaft and output shaft aligned.

Planetary gears are modelled from the movement of the planets with a central drive (or sun gear) and orbiting gears.

Features, benefits and characteristics of planetary gears include: 

  • High quality and very efficient 
  • Maximum power density (the latest designs are capable of handling acceleration torques 40% higher than previous generations) 
  • Can be installed vertically, horizontally or with the output facing upwards or downwards The Easy to install 
  • Optional integrated thermal length compensation available 
  • Extremely smooth running 
  • Quiet operation 
  • Extremely long life span 
  • Positioning accuracy offers maximum compact precision

What Does A Planetary Gear Do?

A planetary gear is used to efficiently transfer power from a motor to an output.

They are designed to provide a much higher acceleration torque but through a compact system.  Low backlash planetary gearheads
