I am new to the forums here.
I have acquired two old Ames lathes.
One is a closed headstock model, probably EH, with at 1AM collet spindle.
The other is an opened headstock design also using 1AM collets. I did get 25 collets with one of the lathes.
These would be nice in my shop for small, precise, high rpm work that I struggle to do on my South Bend 10k.
These are both ball bearing machines, and they both use the same bearings. I took the machines appart and removed the spindles and bearings.
The closed headstock one has what appears to be a retrofitted oiler on the side that feeds the main bearing. The other one had a main bearing jam packed with grease.
After more than a week soaking in carburetor cleaner and a few visits to the parts cleaner at work the main bearings are mostly clean.
The one that was running in grease will spin quietly and smooth until it suddenly stops on some piece of debris that falls off the inside of the cage. So this one is not quite clean yet, and I am not sure if I can ever get all the junk out of it.
The oil lubricated main bearing is quite loud when it spins, and the balls look like they ran in sand.
Both of the rear bearings from these machines are toast.
The main bearings are New Departure 5209, double row angular contact, and they are opened.
Dims: 45 x 85 x 30.2
The rear support bearings are New Departure 773209, single row radial deep groove, and they are double shielded. 45 x 85 x 19
I have looked for these bearings and found many equivalents to the numbers, but I think that these bearings do not include the rest of the numbers to specify characteristics such as ABEC number, and preload.
Does anyone know where I might find such bearings ABEC-5 or 7, with a medium preload (for the double row)? That is what I guess the originals were.
If I can find bearings the restoration will continue.
