Giordano Colombo after repair

This Giordano Colombo spindle was very contaminated with wood debris. The contamination migrated into the bearings causing excessive wear and catastrophic cage failure in bearing #3. The front bearings also showed signs of fretting and the rear bearings were very loose within the housing bore.

Catastrophic bearing failure

In the pictures below you can see how the wood debris worked its way into the spindle assembly, through the labyrinth cover and eventually into the bearings.

Wood debris migrated past through the labyrinth seal, contaminating the entire spindle assembly.

All bearings and seals were replaced with new. O-ring grooves were added to the rear housing bore for proper bearing fit. This Giordano Colombo spindle left High Speed Technologies performing great.
