YEQIN Industrial Sewing Machine Clutch Motor Pulley Slow Speed Down Universal Fit (45mm)

Excelente A1

Fits my consew Sewing Machine Servo Motor. The hardest part of the installation was getting the screw nut off the motor shaft so I could remove the original 75mm pulley. Once the smaller pulley installed, had to shorten the belt to make it work. Read a couple reviews saying the key way was small/tight but wasn’t an issue on the pullley I got. Was able to quickly install new pulley.

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.

I have used these 2 times now. On my Vintage Cornelly Chainstitch machine and my Consew 206... makes the machine speed very easy to control.

Fit my consew servo motor perfectly works well slow it down the difference is I had a m40 size belt and drop to a m36 when buying grab a belt to go with it it thanks

It fit well. No set screws. Metric. Perfect for the sewing machine. Consew servo. Slows it right down.

Attached in minutes to my machine motor. Used with speed reducer. Seiko cw-8b

I bought this to put on the servo for my Consew sewing machine. Unfortunately when I tried to install it I found the key didn't fit. Upon closer inspection I noticed the casting was extremely poor and the keyway was not straight. I had to take a file to the keyway and gently open it up so the key would fit. There were also large burrs on the outer face of the pulley which would result in the pulley not sitting straight on the shaft once the nut was tightened. So I had to file the face of the pulley as well. Once I made these modification it worked fine. The customer should not have to do this though.
