Also not exactly what you're r asking for: This is a $35 backplate and a $45 dollar plain back collet chuck. You can pay $210 dollars to get them with wrench and already assembled. I machined the backplate as is the common way. I stuck through bolts in it, but it could be done more nicely with transfer screws. Anyhow if you want to try it this way, I'll search out the links. I wish I'd bought it a long time ago.
There is this too: Which is exactly what you're asking for. https://www.bealltool.com/products/turning/colletchuck.php

I searched several years ago and could not fine one. I made my own. I am very pleased with it - I use it more than my 3 and 4-jaw chucks. It is an ER40, but same idea.

Yet another ER40 collet chuck for an Atlas
Just completed an ER40 collet chuck for my Craftsman (Atlas) 12-inch lathe. I followed the excellent drawing by Ronald Crowell, Harold Hall's website, and the many YouTube tutorials. This was a real nice learning experience with a variety of operations... boring a precise diameter, internal...

I recently acquired one (well used) from eBay. It turned out to be not exactly ER-32. Just a whisker oversized, or maybe the collets I tried were a fuzz undersized. I think I can trim off the front and make it work. The taper is correct, the collet sits too deep is all. I haven't found any markings on it, brand or otherwise. But it came (supposedly) off a Craftsman/Atlas 12 inch machine, which I have. (1-1/2x8 nose)
I had asked about the collets here, not knowing the proper terminology. There were many replies, mostly suggesting possible alternative collets. A few agreeing with my idea of reducing the nose a few thou so it would tighten. It is common with Sears parts to be a whisker different than 'standard' so you have to go to Sears for parts. That leads me to think it may well be a Craftsman part. There are no other collets, within the knowledge base here, that come close.
The cost was reasonable, far less than $100, even with shipping. But seems to be a rare animal. I scan eBay regularly for 'unusual' tooling, usually every couple of days. In several years of this, I've only seen the one. So grabbed it. . . Since my last stroke, the one that put me in a wheelchair, I have developed a few allergies. Cold, Pain, that sort of thing. Getting old wouldn't have anything to do with it, I'm sure. In any case, I'm waiting for the weather to warm(>80F) up so I can get into the shop to try the collectively agreed on modification. I live in the 'Deep South" so it shouldn't be much longer.

Not exactly what you asked, but I also looked for a ER32 chuck 1-1/2-8 for my SB9.
no luck but what I do use a MT3 ER32 chuck with a drawbar.
very accurate, works for me.
YMMV
Cheers

Yes I’m wanting to use this on my SB10k. I have thought about the MT3 chuck but there are times I have longer thin stock that I don’t want the overhang. With the MT3 chuck and drawbar you cannot pass stock through it. I’m still searching.

You can always make one. Not hard. That's what I did. https://www.hobby-machinist.com/thr...n-er32-chuck-for-the-lathe.73804/#post-619075 You do have to be able to cut a metric 1.50mm thread for the collet nut. Halligan142 has a video on how to make one for a SB lathe. He made an ER40 chuck but the process would be the same for an ER32
