Abstract: A bearing section for an exhaust turbocharger comprises a receiving opening for receiving a shaft of a rotor assembly of the exhaust turbocharger. The bearing section is designed for positioning bearing elements for supporting the shaft. A lubricant circuit is designed for supplying lubricant to the bearing elements. Lubricant channels are formed in the bearing section. In order to reduce a component temperature of the bearing section, a cooling jacket is provided, through which coolant can flow. The cooling jacket comprises a coolant channel, an inlet channel and an outlet channel. The inlet channel issues at a first opening point into the coolant channel and the outlet channel is connected at a second opening point to the coolant channel in such a way that a flow can pass therethrough. A rib is provided in the coolant channel.
