The results of collaborative research with Kindai University were presented at the Tribology Conference 2023 Spring Tokyo organized by the Japanese Society of Tribologists (held from May 29 to 31, 2023).

Our ongoing joint research with Kindai University focuses on "hydrostatic gas bearings (non-contact bearings)" that use "air" as the lubricating fluid, which can be used in clean environments without lubricating oil.

Hydrostatic gas bearing can support rotating shaft without contact by supplying compressed air from an external source, thus reducing the generation of wear debris from the rotating shaft and bearing in manufacturing machinery.

We introduced the relation between bearing clearance and bearing performance by conducting experiments (performance assessment) that change the gap (bearing clearance) between hydrostatic gas bearing with axial directed slot restrictor (jointly developed product/made of resin) and rotating shaft, and then by performing CAE analysis.

We will apply the research results into designing for the practical hydrostatic gas bearings, and contribute to reducing the maintenance load by improving the cleanliness of food production lines and other manufacturing machinery and by extending their service life.
