Review: Good value and well made - Fit perfectly for the motor I purchased. It helped to slow down the speed and increase the torque of my consew machine. Machine is used for lighter weight leather sewing, canvas, and cordura nylon. Went on easy. Good value for the price.
Review: For keyed motor shafts - This pulley has a keyed slot to fix the pulley to the motor shaft, not a set screw. I replaced my Rex servo motor pulley in less than five minutes after some prep work. The pulley is cast aluminum and mine had both casting flash and sharp edges. A small metal file removes those without problem. Check the key slot openings and smooth them if needed. Next, use an impact driver to loosen the pulley nut on the motor shaft (mine was 19mm). If you don't have an impact driver, hold the motor pulley with a thin open-end wrench on the pulley wrench flats. The flats should be on the motor-facing side of the pulley. Remove the motor pulley and do not lose the metal key for the slot. Test the key in the pulley slot before installation. Use a metal file to adjust the slot if needed. Install the 45mm pulley on the motor shaft. Align the slots and insert the key to lock the pulley and shaft together. Replace the pulley nut and washers and tighten. The pulley is a good value for the price, installs easily, and works.

## Questions & Answers

**Q: Does this pulley have a set screw**
A: This is not not a one size fits all pulley. It appears to be a 5/8" pulley. Most commercial machines have 3/4" shafts. It has a keyed slot but is not drilled nor does it come with a set screw. Big misleading add. Does not specify bore.

**Q: I just bought a juki 1181 and its so fast i can barely control it...does this pulley go on my servo motor or the machine?**
A: Put a smaller than existing on the motor to slow it down... or a larger pulley than existing on the machine... or both.

**Q: Will this fit Consew Csm1000 servo motor?**
A: yes it will

**Q: What pulley and belt is needed for a Juki ddl8700?**
A: The one that fits.   It is likely already installed.

### ⭐⭐⭐⭐ Works great but no set screw.
*by D***Y on February 13, 2025*

Reduced speed nicely, but beware it has no set screw. My old pulley used a screw instead of a key. I had to drill and tap for a set screw which is a minor inconvenience if you are able to do such things. Had I to do it over, I would look for a pulley with screw. Changed belt from 40 to a 36. Unknown brand of servo motor. Incidentally I used an automotive v belt which is a little too wide but works fine. Not that much tension required.
