Cutex Speed Reducer (2" and 6" Pulley) for Industrial Sewing Machines

Well made sturdy and a place to grease the main bearing. Used Standard v belt from automotive store.

Worked as expected

casting needed to be cleaned up to make it more adjustablegrease fittings were looseworked as designed

I've used a variety of methods to slow down industrial sewing machines, but, with a brand new Juki I wanted to try a reducer made for this purpose. I was disappointed: While this cast iron reducer does work, it has some problems:1. Being a one-legged assembly, the device is not very sturdy in terms of "tipping" and it's very difficult to get the motor, machine, and reducer all on a plane that will work. Of course, this "tipping" changes as belts are tightened, so it's a lot of back and forth to adjust.2. There's very little adjustment in the reducer itself; I had to spend nearly as much as I did on the reducer in belts before I got sizes that would work with the adjustment range.3. Putting any tension on the sliding tension assembly is also a real chore; the assembly is not very well made\well cast and the sliding parts bind against each other requiring constant loosening or tightening of the single bolt that holds the tension. There's no provision for tightening other than pulling or prying and then trying to lock it down while you pull or pry.4. The single bolt that holds the tension is extremely short and is only holding on by maybe 1.5 threads; it could be much longer, I have no idea why it is like this.5. There's no instructions or hardware. I used 1/4 inch truss head machine screws for mounting. While not having these things is not a huge deal, having a pre-printed template of the hole pattern would help a great deal.6. This is personal preference: I couldn't find a sweet spot with the speed and torque. With a 45mm pulley on my servo motor, there is too much torque through the reducer (It can exert more force than I'd ever put on the machine through the hand wheel) and I could easily see damaging my machine. With a 75mm pulley on the servo motor, it's just not quite as slow as I'd like.I should have stuck to my normal formula of a good quality name brand servo motor with a smaller pulley.

I tried emailing for 2-3 days no response so l gave up the one that l got isn't working right the bearing inside r bad wheel don't turn smoothly of all they got l got the bad one l know they got better ones cos two of my friends ordered one and they work perfectly l know they will will send me an other one but l can't get a hold of them

These things are ok but not great.Do not use automotive v belts, you want fractional horsepower belts that start with the prefix 3L.3L is the width of the belt.For my consew 1260rb, I am using a 3l230 and 3l380 v belt. 230 means a 23 inch belt, 380 means a 38 inch belt. You have to measure your machine as these sizes will differ depending on where you mount the reducer. So if you need a 24 inch belt, search amazon for a 3l240.
