Abstract
The invention is concerned with a sliding-type bearing suitable for use in high-speed rotary machines. The sliding-type bearing has a bearing surface provided with a lubricating oil groove at each of two portions thereof substantially 90.degree. spaced from the point to which the load exerted by the bearing is applied. A chamfer is formed in the portion of the bearing surface near one of the two lubricating oil grooves remoter from the point of the minimum bearing clearance which is determined by the direction of rotation of the shaft and the direction of application of the load by the rotary shaft. This chamfer permits the discharge of the heated lubricating oil to the outside of the bearing thereby to prevent the same from flowing into the point of the minimum bearing clearance.
