The main factor in the decision to use NovaGlide™ or Fusion® bearings is the operating environment. NovaGlide™ bearings are typically more tolerant of process gases and temperature. However, since the NovaGlide™ bearing controller is external to the machine, multiple wire feedthroughs are required for the coil currents and the sensor signals. Fusion® bearings can operate on a minimum of two power wires and therefore the bearing integration is less complex.
