Ares Seiki A6030 Spindle Repair

Ares Seiki A6030 Spindle Repair


When we received this spindle for evaluation, the bearings sounded noisy when rotated by hand. Upon inspection, our technician noted that the entire spindle interior was contaminated with coolant and lubricant. Grease had completely washed out of the front bearing pair and debris from broken cages spread throughout the front of the spindle.Grease in rear bearing pair was partially washed out, but they did not fail. Gripper finger condition looked good.


This was a straightforward repair with no dimensional work or machining required. The following items were addressed in this repair:
  • Replaced bearings, Bellevilles, o-rings and assembly screws
  • Adjust preload, balance, assemble and break in
  • Pass final quality control inspection


Every Northland Tool repair is backed by our 1-year warranty.
