Boost  For Electric & Hybrid Mileage

Addressing the specific requirements of high power density electricmotors for electric and hybrid vehicles, SKF eDrive Ball Bearings enable lower levels of friction and heat dissipation, supporting higher electric motor efficiency and operating speeds.

It is claimed that this solution will allow electric motor and E-powertrain manufacturers to improve the efficiency, power density and battery reliability of motors. Similarly,manufacturers of electric and hybrid vehicles can offer their customers increased mileage, while battery lifetime is extended by a reduction in the number of charging cycles. For example, in a typical electric vehicle, an extra 1% of mileage can be gained by using a set of optimised SKF bearings and seals on the electric traction motor and gearbox compared to conventional alternatives.

Design features include optimised internal geometry, ultra-low friction sealing and a patented, energy efficient polymer cage.
