Timing belt pulley MXL 025 z=20 aluminium

Product Description

Timing belt pulley MXL 025 z=20 aluminium - for MXL belts with a pitch of 0.080" (2.032 mm). Made of hard-anodised aluminium 6082 T6.

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.

The pulley performs well wherever precise motion synchronisation is required: robotics, precision automation, measuring devices, printers.

Aluminium pulley MXL z=20 - low inertia, fast drive

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?

Aluminium has almost three times lower density than steel - the pulley is lighter and has a lower moment of inertia, which means faster acceleration and braking of the drive.

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.
