Kessler 000.673.603 Spindle Repair
The Kessler 000.673.603 spindle is a high speed spindle capable of running up to an astonishing 120,000 rpm. It is able to do this due to being oil mist lubricated and stator driven.
This Kessler 000.673.603 spindle rotated freely when it arrived at Northland Tool and Electronics, but the bearings felt worn when spun by hand in assembly. We noted right away that there was oil was leaking out of the front of the spindle. It seemed as though the spindle had been heavily oiled because it was throughout the entire spindle. After completing the breakdown and evaluation, we noted that the bearings had slight particulate contamination and felt rough when spun by hand. No dimensional deviations were noted for this repair.
The following actions were performed on this Kessler 000.673.603 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
