Schneider SLP-50 Spindle Repair
The Schneider SLP-50 spindle is a workpeice spindle that is grease lubricated and belt driven. It is capable of running up to a speed of 2,000 rpm.
This Schneider SLP-50 spindle felt rough and sluggish when spun by hand incoming. During the incoming inspection we measured runout on the tail was 10 microns, and the face had a runout of 4 microns in assembly. After disassembly and a full evaluation, we found that the #3 bearing was contaminated with a brown particulate. It was also noted that the bare shaft runouts measured much better. No other dimensional deviations were noted for this repair.
The following actions were performed on this Schneider SLP-50 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
- Kiss grind the shaft face
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.
