The electric vehicle grease industry finds its bearings

emerging technologies, energy
Evolving grease formulations help smooth the transition toward electric vehicles. TLT November 2021 Electric vehicles don't require gasoline, but they do require grease. Existing greases are OK for windshield wipers, door hinges, and window winder mechanisms, but the bearings and gears in the drive train are a different story. High operating temperatures and voltages are key concerns. As current densities increase, so does the risk of stray currents that can pit bearings. Typical electric motor speeds, currently around 15,000 rpm, are expected to exceed 20,000 rpm in the near future. /
