Abstract

A device encapsulates a main bearing of a crankshaft. The main bearing is supplied with oil via an oil supply groove. The device has a bearing seat for the main bearing and on its sides which face toward the crank webs of the crankshaft, has oil channels which are open in the direction of the main bearing and in the direction of the crankshaft webs. In the device, the oil channels are sealed off in the direction of the crankshaft webs by sealing disks which are fastened to the bearing seat.
