Finding the right T2.5 pulley

Reading the code16T2.5/12-2(PB) is a T2.5 pulley with 12 teeth (the number after the slash), supplied with a 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.

T or AT?T pulleys suit T-profile belts only. AT belts have a bigger tooth and need AT pulleys, so match the pulley to the letters on the belt.

Tip: For the belt, see our T2.5 timing belts. These pulleys have a pilot bore, ready to be bored and keywayed to your shaft by a machine shop.
