So I bought some ballscrews over the summer-they are just too large. New, Class C5 ground Tsubaki ballscrews, 42 and 43 inches long. I've got them listed on CNCzone for 275$, I'll list them here for 250$ each.

There are three screws, two identical in length and one third that is about an inch longer. They are new with some shelf marks, but no damage, and are wrapped in plastic shrink wrap. The ballnuts are the double-nut with the ground spacer fit to remove any backlash, and are both rebuildable and adjustable.

They're about 50mm diameter-I will take detailed measurements if someone wants them. They're *probably* replacement screws for Okuma milling machines. That's the only reference I can find to the part numbers marked on the screws.

Like I mentioned, I'll sell them for 250$ each plus shipping. They'll fit on a standard pallet, and weigh about 150lbs total palletized weight.

I'm located in Kentucky, around 70 miles due north of Nashville TN, and can arrange freight if needed.

I'm getting tired to tripping over these.

Turns out one of them is most likely used-the other two appear new. None show any wear.

They're 40mm diameter screws with a 10mm pitch. I'm dropping the price to 75$ each.

I'm told by a couple ballscrew rebuilders they are for an Okuma MV-40B, but I can't find much information to back that up. I can provide CAD drawings of the end machining and ballnut, though.

I may be interested too, I'm within driving distance if the other guy doesn't pick them up

Yes, they're still available. I've got two new with shelf wear, and one that's used but I can't tell any damage/wear in it other than it's dirty.

Sorry for the delay in answering, I didn't get any notifications for the thread here.

Got the two new screws shipped out today.

I have one screw left-it's used and has a little corrosion damage on the keyed end of the shaft, where the pulley rides. Nothing serious, just were it was wrapped in tape for so long riding the shelf.
