  • Very economical and reliable method of speed change
  • Allows the user to find the ideal speed without changing sheaves and belts; especially important on applications where final driven speed is critical and difficult to attain with two fixed-diameter sheave
  • Speed range within the ratio is infinite, and speed change is accomplished quickly, while the drive is running
  • Can be used as a highly efficient belt tensioner, with no adjustment necessary
  • Offers a form of “soft start,” eliminating belt slip and premature wear
  • On belt drives with inherent high torque start-up requirements
