SNK Spindle Repair

SNK Spindle Repair

This SNK spindle is oil mist lubricated, spline driven, and capable of running up to 2,000 rpm.


This SNK spindle was sent in and completely disassembled and evaluated.  Upon closer inspection, we noted that the bearings had failed from contamination.  The taper chrome was starting to chip, and it has 14-16 microns of run out.  Lastly, the taper face was damaged as well.  No other dimensional deviations were noted for this repair.



The following actions were performed on this SNK spindle:

  • Clean, inspect overall dimensions
  • Replace bearings, bellvilles, o-ring, star washer, and assembly screws
  • Grind, chrome plate, and finish grind the 50 taper
  • Kiss grind the taper face



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.
