Cytec Spindle Repair

CHALLENGE

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

SOLUTION

The following actions were performed on this Cytec spindle:

• Clean, inspect overall dimensions
• Replace bearings with sealed

RESULT

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.
