Product Description
Timing belt pulley H 150 z=21 steel - for H belts with a pitch of 1/2" (12.7 mm). Made of C45 steel.
The pilot bore allows the pulley to be bored precisely to the shaft size and the fit required by the machine, to H7 tolerance. The keyway is cut on a slotting machine according to DIN 6885.
The pulley performs well wherever precise motion synchronisation is required: heavy industrial drives, agricultural machinery, machine tools, presses.

FAQ
How do you choose a pulley for a toothed belt?
The key is matching the series (H = pitch 1/2" (12.7 mm)) and the belt width (150 mm). The drive ratio is calculated by dividing the number of teeth of the driven pulley by the number of teeth of the driving pulley.
