The influence of the magnetic field on magnetic fluid in the bearing dominantly appears in the increase of the effective viscosity and leads to the variation of the velocity. According to this result, the static characteristics of this type of journal bearings are calculated under the hypothesis of infinitely long bearings. It is known that the load capacity is improved with the increase of the magnetic intensity, the saturation magnetization intensity and the dimension of magnetic particles; but the shaft center locus remains nearly the same as ordinary bearings. It is also known that a suitable combination of base fluid viscosity and magnetic fluid viscosity can reach a maximum load copacity under a certain magnetic field intensity.
