Electric vehicles are increasingly common on the world’s roads, thanks to tighter emission requirements and concerns about the future of fossil fuels.
While many of these EVs offer modest performance, an increasing number of manufacturers are exploiting the near-instant torque delivered by electric motors to produce high-performance vehicles.
SKF eDrive Ball Bearing technology has been developed for use in the full spectrum of EVs and has recently been used in the Mercedes-Benz SLS AMG Coupé Electric Drive supercar, a vehicle whose four electric motors make it capable of producing 552 kW and of accelerating from 0 to 60 mph in 3.9 seconds.
SKF was first approached to develop a bearing arrangement for use in the motors of Daimler electric vehicles in 2010. An arrangement was subsequently designed by Daimler, produced by SKF in Italy, assembled by EM-motive in Hildesheim, Germany, and then tested by Daimler and AMG.
The bearing arrangement was successfully incorporated and the impressive AMG vehicle is now on the market.
