What is the Use of the V-belt Idler Pulleys?

V-belt pulleys are devices that transmit power between axles by using a v-belt, a mechanical linkage with a v-shaped cross-section. These pulleys have grooves located around the circumference, which help guide and gain traction on a v-belt, and are a notable upgrade from round or flat belt transmissions. V-belt idlers provide excellent traction, speed, and load capabilities.

V-belt idler pulleys are used in a wide variety of applications, including:

  • Material handling processes
  • Hoisting equipment
  • Fitness and lifting equipment
  • Extra support to reduce belt vibration in other applications
