Endeavor Technologies will completely rebuild your Mitsubishi SJ-VKRS30-04ZM spindle motor to like-new condition. Don’t settle for having your spindle motor “repaired.” Send it to Endeavor Technologies, Mitsubishi Electric Automation’s service partner, to be rebuilt to factory specifications.
Repair of your Mitsubishi SJ-VKRS30-04ZM spindle motor
Mitsubishi spindle motors use special radial bearings. These bearings are designed to operate at elevated speeds and higher levels of precision than ordinary electric motor bearings. We stock OEM bearings, PLG assemblies, terminal blocks, fan motors, original castings, and other components.
Rebuilding your Mitsubishi SJ-VKRS30-04ZM spindle motor may require replacing the shaft if a bearing has failed catastrophically. This may also be required if the output shaft has become badly worn. To expedite delivery, we stock complete new shafts. The experts in our machining department will precision grind all the critical diameters to factory tolerances.
If the motor winding has failed, our winding department will rewind it with class H insulation. This is done while 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. It is just as important to measure and monitor the amount of vibration the motor produces during full speed testing.
Full speed run-in
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-VKRS30-04ZM will be run through a break-in period to full speed. This is done using one of our Mitsubishi CNC simulators. Learn more about our testing procedure.
Service reports as well as failure reports are available on request.

No one offers better service and support for Mitsubishi spindle and servomotors because no one else has made the same commitment to test equipment, training, and inventory. Learn more about Endeavor Technologies service for Mitsubishi spindle motors.
If your Mitsubishi SJ-VKRS30-04ZM 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-VKRS30-04ZM motor to us for comprehensive testing or rebuilding.
