Product Description
Timing belt pulley PolyChain PCB 8M 21 z=38 Steel - for HTD 8M / PolyChain GT belts with a pitch of 8 mm (HTD). Made of C45 steel with a profile optimised for Gates PolyChain GT polyurethane belts.
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.
Used in machines requiring accurate motion transmission: industrial drives, heavy machinery, production lines.

FAQ
How do you choose a pulley for a toothed belt?
The key is matching the series (8M = 8 mm pitch (HTD)) and the belt width (21 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.
