Cytec Spindle Rebuild

Coolant contamination had worked its way through the front and rear labyrinths over time. The coolant mixes with the grease of the bearings and slowly compromises the lubrication. The thin film of lubricant between the balls and the raceways is compromised and the balls make contact with the races. This causes damage that continues to deteriorate the bearings until failure.

Possible cause of failure:

  • Bearing failure from front and rear contamination

Repair action:

  • Clean, inspect overall dimensions
  • Replace bearings with sealed
  • Adjust preload, balance, assemble and break in
  • Final quality control inspection
