H profile taper bush timing pulleys
Available items: approx. 1-2 working days
Size interpretation: number of teeth of the timing pulley / pulley profile / maximum belt width (inch) / compatible taper bush type number
Nominal pitch diameter calculation (mm): number of teeth x 12.7 / 3.14
The advantage of taper bush timing pulleys (toothed belt pulleys) is that a pulley with a given diameter can be easily matched and replaced with different bore diameters by using different taper bushes for various shaft sizes. If the mounting position – and therefore the shaft diameter – changes, the existing pulley can be reused by purchasing a new taper bush only; replacing the pulley itself is not necessary. The pulleys listed below are supplied without taper bush, which must be ordered separately!
Pulleys up to 48 teeth are supplied with flanges, from 60 teeth upwards they are supplied without flanges.
The material of H taper bush timing pulleys is steel up to 48 teeth, and cast iron from 60 teeth; the pulley is phosphated for corrosion protection.
