Gearboxes, also known as enclosed gear drives or worm gear speed reducers, are mechanical power transmission drive components that can drive a load at a reduced fixed ratio of the motor speed. The output torque is also increased by the same ratio, while the horsepower remains the same (less efficiency losses.) A 10:1 gearbox outputs approximately the same motor output horsepower, motor speed divided by 10, and motor torque multiplied by 10. Similar performance metrics are provided by 20:1 gearboxes and other ratios.

Worm gearboxes contain a worm-type gear on the input shaft, and a worm-type mating gear on the output shaft. Worm gearboxes also change the drive direction.

• Right angle gearboxes with right-hand output shafts
  
  
• Dual shaft gearboxes (both right and left output shafts)
  
  
• New! ... Hollow shaft worm gearboxes (all the way through both sides)
  
  
• IronHorse gearboxes utilize C-face mounting interfaces for C-face motors
  
  
• Worm gear reducer mounting bases are also available for ease of installation

• Three output types: Dual Shaft, Right Hand Shaft and Hollow Shaft
  
  
• Four frame sizes: 1.75", 2.06", 2.37", 2.62"
  
  
• Six ratios: 5:1, 10:1, 15:1, 20:1, 40:1, 60:1
