Fully refurbished Mitsubishi spindle motor SJ-11XW8Z

Short Report: Successful Repair of Two Mitsubishi Spindle Motors

Recently, we successfully repaired the following Mitsubishi AC spindle motors:

  • SJ-11XW8Z
  • SJ-18.5BW4

Take a look at the before-and-after images in the slideshow!

Both motors were heavily contaminated, with worn-out ball bearings and fluctuating encoder signals. But we fixed it! πŸ‘‡

The following work was carried out:

  • Preventive overhaul: Replacement of all defective and worn parts.
  • Renewal of ball bearings and seals.
  • Intensive cleaning: Stripping, degreasing, and repainting.
  • Extended testing: Long-term testing on our test benches, followed by final adjustments.

Standard repair time: 7 working days

🌍 Environmental Awareness: Every repair extends the lifespan of these machines, reducing the need to consume new resources. Repairing instead of discarding – good for the environment, good for the future! 🌱
