HTD 8M timing pulleys

8M timing pulleys work with HTD 8M belts with a rounded tooth and an 8 mm pitch. This is the core profile for industrial drives - it is found in production lines, conveyors, pumps, compressors and heavy machinery.

HTD 8M timing pulleys - a quiet high-power drive instead of a chain

An 8M drive transmits high power with moderate pulley diameters, runs quietly and needs no lubrication, which is why it often replaces a chain. 8M belts and pulleys are readily available, which makes servicing easier. Smaller pulleys are made of C45 steel, and larger ones of grey cast iron - the tooth profile is the same, so both run with the same belt. The Taper-Lock version allows the pulley to be replaced quickly without shaft machining.

HTD 8M timing belt pulleys in several widths, for a bush and with a pilot bore

8M pulleys for several belt widths, in the Pilot bore and Taper-Lock subgroups. The belt width is given in the pulley name. 8M belts can be found in the Timing belts category.

Choosing the width and belt - customer questions about HTD 8M synchronous pulleys

How do I choose the width of an 8M pulley?

The pulley width must match the belt width, e.g. an 8M belt 30 mm wide requires an 8M 30 pulley.

Does an 8M pulley fit a PolyChain 8MGT belt?

No. PolyChain GT belts have a different tooth profile and require pulleys from the PolyChain 8MGT timing pulleys group.
