ASK MATT Q&A - INSIGHTS FROM AN INDUSTRY EXPERT

Topic: Hybrid and EV Wheel Bearings 

QUESTION: We know that Hybrid Electric Vehicles (HEVs), Plug-In Hybrid Vehicles (PHVs), and Electric Vehicles (EVs) are heavier than comparable gasoline powered vehicles. Can this have any effect on the lifetime and performance of the wheel bearings?

ANSWER: Absolutely, the service life of a wheel bearing in one of these vehicles could be shorter. The added curb weight needs to be supported by the suspension and chassis, and this can take a toll over time. The bearings could be more susceptible to damage from an impact, whether it’s a curb strike or a nasty pothole.

Topic: Hybrid and EV Wheel Bearings

QUESTION: Is there a fundamental difference between the wheel bearings on a BEV or EV versus a comparable gasoline-powered vehicle, or are they nearly the same?

ANSWER: No, in most cases they’re the exact same. Some OEMs have experimented with adding rows of ball bearings to help carry the added weight, but it’s not common.
