V-Belt & Pulley Selection

Ask us for help in recommending the right belts for your application

The following minimum information is required to allow selection of the correct V-belt system parts:-

  • Speed (rpm) of drive and driven shafts
  • Motor power (HP or KW)
  • Type of "prime mover" or motor and starting style for electric motors
  • Shaft diameter of drive and driven shafts (inch or metric)
  • Duty cycle (to allow selection of a suitable service factor)
  • Any dimensional constraints or expected center distance between shafts
