Abstract
A product for use with a turbocharger is disclosed. According to a number of variations, the product may include a bearing housing with a bearing assembly positioned in the bearing housing. A shaft may extend through the bearing assembly for rotation. A turbine wheel may be exposed to high temperature exhaust gases and may be connected to the shaft. The product may include a number of features to manage heat transfer and protect the bearing assembly from excessive temperatures that may otherwise result from exposure to the exhaust gases.
