Nakamura-Tome Spindle Repair

Nakamura-Tome Spindle Repair


This Nakamura-Tome spindle arrived at our facility for a breakdown and evaluation.  After disassembly, we noted that the front bearings were heavily contaminated from use.  The taper showed significant wear and both shaft shoulders have runout.  The pulleys arrived very dirty and the spindle drains were all plugged with contaminants.



The following actions were performed on this Nakamura-Tome spindle:

  • Clean, inspect overall dimensions
  • Replace bearings
  • Kiss grind taper and shaft shoulders
  • Clean out all drains
  • Clean the pulleys
  • Replace o-rings



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.
