HTD 5M pilot bore timing pulleys

5M pilot bore timing pulleys work with HTD 5M timing belts with a 5 mm pitch. A timing belt transmits drive without slip, like a chain, but runs more quietly, needs no lubrication and practically does not stretch during operation.

HTD 5M pilot bore timing belt pulleys - rounded tooth, bore for an H7 fit

The rounded HTD tooth profile spreads the pressure over a larger area than the older trapezoidal profile, so the drive transmits more torque and runs more quietly. You bore out the pilot bore exactly for your shaft to an H7 tolerance and cut the keyway to DIN 6885 - the pulley fits any design. Smaller pulleys are made of wear-resistant C45 steel, and larger ones of hard-anodised 6082 T6 aluminium - they are light and reduce drive inertia.

HTD 5M timing pulleys with a pilot bore for automation and packaging machines

HTD 5M timing pulleys with a pilot bore, for several belt widths. They are used in industrial machinery, automation and packaging equipment. Pulleys mounted on a taper bush can be found in the Taper-Lock group, and HTD 5M belts - in the Timing belts category.

Questions and answers: a T5 belt on an HTD 5M synchronous pulley

Will a T5 belt run on a 5M pulley?

No. Both have a 5 mm pitch, but the T5 belt has trapezoidal teeth, while 5M has rounded ones. The pulley profile must match the belt profile.
