Endeavor Technologies will completely rebuild your Mitsubishi SJ-N0.4AG spindle motor to like-new condition, regardless of the failure. Don’t settle for having your Mitsubishi SJ-N0.4AG spindle motor “repaired”. Send it to Endeavor Technologies to be completely rebuilt to factory specifications, using original OEM parts.
Mitsubishi spindle motors utilize radial bearings specially designed to operate at elevated speeds and higher levels of precision than ordinary electric motor bearings. In addition to the OEM bearings, we stock PLG assemblies, terminal blocks, fan motors, original castings, and other components.
Rebuilding your SJ-N0.4AG spindle motor may require replacing the shaft if a bearing has failed catastrophically, or if the output shaft has become badly worn. We stock complete new shafts to expedite delivery, and the experts in our machining department will precision grind all the critical diameters to the factory tolerances.
If the motor winding has failed, our winding department will rewind it with class H insulation, carefully observing the original factory winding specifications.
All spindle motors are dynamically balanced before being assembled. Balancing is a critical aspect of rebuilding any spindle motor.
This motor must be assembled to Mitsubishi’s demanding dimensional tolerances to achieve the expected life. After adjusting the PLG and verifying the assembly accuracy, your spindle motor type SJ-N0.4AG will be run through a break-in period to full speed with one of our Mitsubishi CNC simulators. Learn more about our testing procedure.
Service reports as well as failure reports are available on request.
If your SJ-N0.4AG spindle motor was “repaired” by an unauthorized repair shop and still doesn’t work, or failed pre-maturely, it’s not too late! Send your Mitsubishi SJ-N0.4AG servomotor to us for comprehensive testing or rebuilding.
