The machine has these components

1. Pure iron core (>99.95% iron)
2. Stainless shaft
3. Stainless bearing
4. Stainless bearing mount holder

The first type is the whole-iron core and the second type is two -halves iron core. The two are essentially the same except that the two-halves iron core has the iron core split into two halves and have to be held together by some bolting arrangement. The bolting arrangement shown in the drawing can be modified to something better.

Precision required is >0.01. Shaft central position must not be less than 0.001 precision for all cases.

Attached is the detailed drawing.

We will need some sample and will be paying for the samples.

PLEASE ONLY SERIOUS QUOTES REQUIRED.
