Metric Timing Belt Pulleys

Metric timing belt pulleys

Toothed pulleys for metric HTD and polyurethane timing belts, from Dunlop / Optibelt. Choose a profile, or search by the pulley code, such as 12-5M-09F(PB).

Choosing the right metric timing pulley

Three things decide which timing pulley you need: the belt profile, the number of teeth and the width.

  • Reading the code12-5M-09F(PB) is 12 teeth, 5M profile, for a 9mm belt, flanged (F), pilot bore (PB). A bush size in brackets means taper lock.
  • Match the profileHTD pulleys suit HTD and Megadyne RPP belts. Supertorque, T and AT belts each need their own pulleys, so match the letters on the belt.
  • Teeth and ratioThe tooth count sets the pulley size and the speed ratio. Count the teeth on the old pulley and keep the same count to keep the same speed.
