Abstract
A crankshaft bearing for internal-combustion engines is provided in an internal-combustion engine housing made of a light metal alloy and comprises a bearing bore for a crankshaft journal of a crankshaft. The crankshaft bearing is provided with a device that reduces the increase in bearing play that occurs during the operation of the internal-combustion engine. This device includes a compensating element which is provided between the bearing bore and the crankshaft journal and has a relatively high coefficient of expansion.
