Kugel ball nature: hydrodynamics-mathematics-design
The Kugel fountain, where a sphere sits in a fitted socket fed by a thin film of pressurized water flowing between the sphere and the socket, was treated as a bearing without referring to any mathematical or practical evidence that can support this idea.

UNIVERSAL STAND FOR STUDYING SEALING AND BEARING UNITS OF COMPRESSOR MACHINES [PDF]
The proposed stand is designed to test sealing and bearing units of various types, because these units, regardless of their type, require almost the same auxiliary stand systems, as well as practically the same measurement system.

The Structural Optimum of Hydrostatic Thrust Bearings to Avoid Cavitation
Cavitation of oil film is harmful for all kinds of hydrostatic bearings, so the method to avoid cavitation in hydrostatic thrust bearings by optimizing the structure of bearings is proposed in this study. Based on the pressure distribution expressions of
