Product Description
Timing belt pulley PolyChain GT PC 8M 12 z=34 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.
Typical applications: industrial drives, heavy machinery, production lines.

FAQ
How does PolyChain GT differ from an HTD 8M pulley?
The pitch is identical (8 mm), so the pulleys have the same overall dimensions - but the tooth profile is optimised for the Gates PolyChain GT polyurethane belt. PolyChain and HTD 8M pulleys are not interchangeable - use only PolyChain pulleys with a PolyChain belt.
Can I use an HTD 8M belt on a PolyChain GT pulley?
We do not recommend it. The tooth profile of a PolyChain pulley differs from that of a conventional HTD pulley - the belt will fit on the pulley but will not sit optimally in the teeth, which will shorten its service life and may lead to tooth skipping under load.
