The long lasting trend to minimize CO2 emissions leads to several changes in the powertrain. Besides downsizing, high ratio spreads, or hybrid technologies for example, the number of rolling bearings is increasing. Their benefit is the lower friction loss compared to plain bearings and they suit better to start-stop systems as well with reduced wear when starting from standstill. Furthermore rolling bearings need less oil pump power so that the fuel consumption decreases again.
