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 (100 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.
How can you recognise a worn pulley groove?
If the bottom of the groove is shiny, the belt has bottomed out and no longer wedges against the flanks - the pulley needs replacing. Profile gauges are used for checking.
