Metric pitch timing pulleys

Metric pitch timing pulleys work with belts whose pitch is given in millimetres - the number in the profile designation is the pitch, e.g. 8M means 8 mm and T5 means 5 mm. Metric synchronous drives are now the standard in new machines: from 3D printers and CNC axes to heavy industrial drives.

Metric timing pulleys - spare parts and easy drive servicing

Metric belts and pulleys are widely available, so the drive is easy to service, and parts from different manufacturers are interchangeable within a profile. You match the pulley material to the task: hard-anodised aluminium in light, fast drives, C45 steel where high torques act, and grey cast iron in the largest pulleys. In the industrial profiles you can also choose Taper-Lock pulleys, mounted without shaft machining.

HTD, T, AT and PolyChain GT metric pitch synchronous pulleys

Pulleys for the HTD profile (3M, 5M, 8M, 14M) with a rounded tooth that transmits high torque and runs quietly, for the trapezoidal T profiles (T2.5, T5, T10) to DIN 7721 and the reinforced AT profiles (AT5, AT10), as well as POLY CHAIN pulleys for Gates PolyChain GT belts. In every profile, the pulleys are divided into Pilot bore and Taper-Lock.

HTD, T or AT? Customer questions about metric timing belt pulleys

Are the HTD 8M and T10 profiles interchangeable?

No. They differ in pitch and tooth shape - HTD has a rounded tooth, and T a trapezoidal one.

What is the difference between an AT5 and a T5 pulley?

Both have a 5 mm pitch, but the AT5 belt has a wider tooth and requires a pulley with a different groove profile. A T5 pulley does not work correctly with an AT5 belt.
