Howa Spindle Repair

Howa Spindle Repair

This Howa spindle is grease lubricated and capable of operating up to 15,000 rpm.


When this Howa spindle arrived at Northland Tool and Electronics it was already completely disassembled.  Upon inspection we noted that the bearings were very worn, the bearing spacer was bent, and the taper measured out of ISO specifications.  The drawbar bellevilles were also very worn and needed to be replaced.  No other dimensional deviations were noted for this repair.



The following actions were performed on this Howa spindle:

  • Clean, inspect overall dimensions
  • Replace bearings, balls, and bellevilles
  • Manufacture a new front spacer
  • Kiss grind 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.
