Notes

  1. Please indicate whether it is wet type (S) or dry type (T).
  2. Applied hole location on outer body is either of (A) EKE 1 - 2, (B) EKE 4 - 161 (C) EKE 250 - 1000.
  3. Please indicate dimension of the part marked. (If nothing is indicated, product with prepared hole shall be delivered).
  4. Since product with prepared knock pin hole is delivered, it shall be processed at assembly.
  5. For this product, generator of over excitation type which applies 2 - 4 times of rated voltage at power supply (approximately 1 second) shall be utilized.
  6. No power supply unit and power unit are attached, which shall be ordered separately with reference to electromagnetic clutch / electric component for brake.
