Finding the right 3M pulley

Reading the code10-3M-06F(PB) is 10 teeth, 3M profile, for a 6mm wide belt, flanged (F), pilot bore (PB).

Size and speedThe number of teeth sets the pulley size and the speed ratio. Count the teeth on the old pulley and match the width to your belt.

HTD or Supertorque?These pulleys suit round-tooth HTD and RPP belts. Supertorque S3M belts have a different tooth shape and need their own pulleys.

Tip: For the belt, see our 3M timing belts. Taper lock pulleys show the bush size in brackets; choose a metric taper lock bush in that size with a bore to fit your shaft.
