Timing belt pulley 5M 15 z=26 steel

Product Description

Timing belt pulley 5M 15 z=26 steel - for HTD 5M belts with a pitch of 5 mm (HTD). Made of C45 steel.

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.

Designed for synchronous drives in: industrial machinery, automation, packaging equipment.

FAQ

What materials do you use for pulleys?

C45 steel provides high mechanical strength and fatigue resistance - the right choice for heavily loaded drives with frequent torque peaks.

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.

What is a pilot bore and how is it rebored?

A pilot bore is a technological bore smaller than the target shaft diameter - a turner rebores it precisely to the specific shaft, to H7 tolerance. The keyway is cut on a slotting machine according to DIN 6885.

How do you align pulleys correctly?

The grooves of both pulleys must lie in one plane. Check this with a straightedge or a laser alignment tool. Even a slight lateral misalignment causes rapid wear of the belt's side edges.
