# Bearing system

## Abstract

A bearing system is capable of securing load capacity without increasing resistance for a slide bearing using a fluid having a high viscosity and a fluid having a low viscosity. The bearing system includes a slide bearing lubricated by oil and a refrigerant (a CO 2 refrigerant) and supporting a rotation shaft; oil passages for supplying the oil to a first region of a sliding surface of the slide bearing; and a refrigerant passage provided away from the oil passages in an axial direction and supplying a refrigerant to a second region different from the first region in the sliding surface, and the slide bearing is formed such that an inner diameter of the second region is smaller than an inner diameter of the first region.
