Satisloh Spindle Rebuild

Satisloh Spindle Rebuild

Northland Tool & Electronics has worked closely with several optical lens grinding companies to give them an option for the repair of their polishing spindles. When we found that most optical spindles were being returned to the OEM’s for repair, many times overseas, or just replaced with new, Northland Tool & Electronics worked closely with several companies to make sure our repairs met the standards needed for the process. We now repair all types of optical grinding spindles. Please call us to discuss how we can help you save downtime and money.


When this Satisloh spindle arrived at Northland Tool and Electronics we completed a full breakdown and evaluation.  Upon assessment of the spindle, we noted that the bearings were worn and that the power wire was broken.  No dimensional deviations were noted for this spindle.




The following actions were performed on this Satisloh spindle:

  • Clean, inspect overall dimensions
  • Replace bearings, seals, and broken wire



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.
