Timing belt pulley PolyChain GT PC 8M 12 z=22 Steel

Product Description

Timing belt pulley PolyChain GT PC 8M 12 z=22 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

Do you ship pulleys from stock?

The stock level is shown above the price and may vary depending on the warehouse.

What materials do you use for pulleys?

At the same width, a PolyChain GT belt transmits considerably more torque than a conventional HTD belt. It does not produce dust, is resistant to oils and requires no lubrication.

Does shaft runout damage pulleys?

Yes - shaft runout causes cyclic jerking of the belt, which leads to cracking of the pulley hub and accelerated belt wear. Before mounting the pulley, it is worth checking the shaft runout with a dial indicator.

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.
