Notes
- Initial torque is 60% of rated torque
- Since product with prepared coupling pin hole is delivered, it shall be processed at assembly.
- Please indicate dimension of the part marked. (If nothing is indicated, product with prepared hole shall be delivered).
- For this product, power unit of over excitation type which applies 2 - 4 times of rated voltage at power supply (approximately 1 second) shall be utilized.(Which shall be ordered separately with reference to electromagnetic clutch / electric component for brake.)
