From the present study it can be concluded that water-lubricated journal bearings utilizing silicon carbide against itself offer good performance. Moderate performance can be achieved with an all-alumina sliding pair, provided that the loads remain low and that a high surface quality can be ensured...

The dynamic performance of a new high-speed spindle supported by water-lubricated hybrid bearings is experimentally studied on a test rig. The present design allows the speed of the spindle up to 30,...
This paper describes a mixed elastohydrodynamic lubrication (EHL) model for finite length elastic journal bearings. The finite element method was employed to discretise the coupled system of 2D–3D Reynolds-structure equations and to compute Stribeck curves at constant load. As underrelaxation strategies...
Bearings lubricated by process fluid of pump (mainly water) are used for journal bearings of vertical mixed flow pumps to supply city water or drain rainwater. The material of bearings is porous sintered silicon carbide (SiC) and of the ... Yoshikazu Kimura,Ken'ichi Sugiyama,Hideki Kan'no,....
This paper presents the development of a numerical model for high speed and water lubricated journal bearings with different boundary slip arrangements. The effect of boundary slip and its possible mechanism are analyzed and discussed. The results suggest that a suitable combination of slip/no-slip ...
So far the present invention has been discribed as being applied to the journal bearings, but it is to be understood that it may be also applied to the plain bearings such as thrust bearings which may be considered as a portion of the bearings described above, provided the diameter of the...
