These are 8M HTD taper lock timing pulleys in grey cast iron for HTD belts with an 8mm pitch. The range covers 70 models from 22 to 192 teeth, for 20, 30, 50 and 85mm wide belts.

Each pulley has a tapered bore that takes a taper lock bush. The bush is machined to your shaft size and keyway, and it clamps the pulley to the shaft when its screws are tightened. The last number in each model code is the belt width in millimetres.

Where this product is used

  • Synchronous drives where the driven shaft must keep in step with the driver
  • Indexing and positioning drives
  • Conveyor and material handling drives
  • Machinery drives with torque loads that would make a V-belt slip
  • Replacement pulleys on existing 8M HTD belt drives

Features

  • Taper lock hub that takes a separately sold taper lock bush
  • HTD tooth profile with an 8mm pitch for 8M HTD belts
  • Grey cast iron construction

Choosing the right option

Choose the pulley by belt profile (8M 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.

Then choose the bush. Where two series are, either fits. Order a bush of that series with the bore and keyway you need: see the metric cast iron taper lock bushes or imperial cast iron taper lock bushes, or the metric steel taper lock bushes or imperial steel taper lock bushes.

Fit the bush in the pulley hub, slide the assembly onto the shaft and align the pulley with its mating pulley. Check the two pulleys are in line with a straight edge before fitting the belt.

Fit the belt by moving the shafts closer together, not by levering it over the flanges or teeth.
