Schneider SLG-120 Spindle Repiar
This Schneider SLG-120 spindle is grease lubricated, pulley driven, and capable of running up to 15,000 rpm.
This Schneider SLG-120 spindle was noisy when spun by hand incoming. After disassembly and evaluation, we noted that the #4 bearing felt rough when spun by hand. There was some light scoring on the bearing journals and some slight egging in the rear housing (+6/+10µ). There were no other dimensional deviations noted for this repair.
The following actions were performed on this Schneider SLG-120 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
- Kiss grind the front and rear bearing journals
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.
