The assembly is ready to use, easy to install and interchangeable with current units. It includes a roller bearing, as opposed to a plain bearing, which offers several benefits, including significantly increased power density and a reduction of oil flow and hence oil pump size.
Plain bearings require a separate oil supply, which must also be pressurised for lubrication; SKF's Gear Bearing Unit, however, requires only oil mist lubrication, so optimised oil metering is all that is needed.
