Fryer TC-40H Spindle Repair

The Fryer TC-40H is a CNC horizontal machining center.  It can come fitted with this grease lubricated and belt driven spindle capable of running up to 8,000 rpm.


This Fryer TC-40H spindle rotated freely, but the bearings felt worn when spun by hand incoming.  Once we completed a full disassembly and evaluation, we noted that the grease in the rear bearings had been washed out by coolant and flooded into the front bearings.  The lack of grease from coolant contamination caused the ball cage to overheat and deteriorate.  No dimensional deviations were noted on any critical surfaces.



The following actions were performed on this Fryer TC-40H spindle:

  • Clean, inspect overall dimensions
  • Replace bolts, bearings, and o-rings



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.
