- (*1): This is the numerical value when a magnetic fluid of standard vacuum specification (A type) is used. The value is different when a magnetic fluid of anti-corrosion specification (F type) or low vapor pressure and anti-corrosion specification (U type) is used.
- (*2): The allowable rotation rate when no load is applied to the shaft.
- (*3): The allowable rotation rate when the allowable radial load is applied.
-
(*4): The maximum axial load that can be applied to the center of magnetic fluid seal shaft.
If the load combined with the radial load is applied, or if the load point is off the center of the shaft, please contact us from the Inquiry Form for the magnetic fluid and describe the load conditions in the form. -
(*5): The maximum radial load that can be applied to the shaft end of magnetic fluid seal.
If the load combined with the axial load is applied, or if the load point is far from the shaft end, please contact us from the Inquiry Form for the magnetic fluid and describe the load conditions in the form. - (*6): Starting torque is the maximum load torque upon starting of rotation. This is a reference value and not a guaranteed value. Recommended load torque for selecting a motor is about three times as high as the value described above.
