Jagura Spindle Repair

Jagura Spindle Repair


When this Jagura spindle arrived at Northland Tool and Electronics we completed a full breakdown and evaluation of the spindle.  Upon inspection, we noted that the front bearings failed due to contamination.  We also measured the critical dimensions (bearing journals, housing, taper, etc.) and found two unacceptable deviations.  First, the shaft ID tool taper had 10 microns of runout and will need a kiss grind.  Second, the pulley taper had 4 microns of runout and will need a kiss grind as well.  No other dimensional deviations were found.



The following actions were performed on this Jagura spindle:

  • Clean, inspect overall dimensions
  • Replace bearings
  • Kiss grind shaft ID tool taper
  • Kiss grind pulley taper



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.
