# Bearing system

## Abstract

A bearing system is capable of accurately and simultaneously securing a load capacity of a slide bearing and reducing friction without complicating control. The slide bearing of the bearing system includes: two groove portions that are formed on a sliding surface thereof and extend in a radial direction and a circumferential direction, and these groove portions divide the sliding surface of the slide bearing into a plurality of divided sections in an axial direction. The slide bearing also includes: a discharge hole that is formed in the groove portions to discharge a fluid from the slide bearing; and supply holes for supplying the fluid to the divided sections, which are divided by the groove portions. The slide bearing further supplies oil and CO 2 refrigerant having different viscosities from the respective supply holes, to the one divided section of the plurality of divided sections.
