Selecting and fitting

Choose the pulley by belt profile (5M HTD), belt width and number of teeth. Divide the driven teeth by the driver teeth to find the speed ratio. Both pulleys on a drive must have the same tooth pitch as the belt.

The last number in each model code is the belt width in millimetres, so 22-5M-15PB is for a 15 mm wide belt. Related pilot bore pulleys: 5M HTD Pilot Bore Timing Pulley, Aluminium, 44 to 72 Teeth, 9 to 25 mm Belt Width, 3M HTD Pilot Bore Timing Pulley, 18 to 72 Teeth, 9 and 15 mm Belt Width and 3M HTD Pilot Bore Timing Pulley, Aluminium, Single Flange, 10 to 15 Teeth, 9 and 15 mm Belt Width.

Pilot bore pulleys are supplied with a starter hole. Have the pulley bored and keywayed to suit your shaft, keeping the bore concentric with the pulley, and add a set screw over the keyway.

Fit the belt by moving the shafts closer together, not by levering it over the flanges or teeth. Set the belt tension to the belt maker's recommendation and check it again after a few hours of running.

Dimensions are as listed for each model and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
