KO Lee Cartridge Spindle Repair

This KO Lee Cartridge spindle is grease lubricated, belt driven, and capable of running up to 5,000 rpm.


This KO Lee Cartridge spindle was noisy when spun by hand incoming.  After a thorough breakdown and evaluation, we noted that there were chips at the end of the OD Taper.  We also noted that there was contamination throughout the spindle, which caused the bearings to fail.  No dimensional deviations were noted for this repair.



The following actions were performed on this KO Lee Cartridge spindle:

  • Clean, inspect overall dimensions
  • Replace bearings, o-rings, and assembly screws
  • Chamfer OD Taper end



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.
