Innovative bearing solutions play a key role in sustainable mobility by making powertrains and chassis systems more energy efficient.
In electrified vehicles, all energy saved translates into increased range. Vehicle developers are therefore looking closely at every bearing location as they seek to optimize friction performance and enhance utility for the customer. Schaeffler understands this, and is now presenting two further product innovations designed specifically for electric vehicles: The first is the TriFinity product, a triple-row wheel bearing designed for use in electrified powertrains. It is no bigger than standard two-row ball bearings, but is able to transfer greater axle loads, while also offering a longer service life and improved rigidity. Moreover, this ball bearing design provides an alternative to preloaded tapered roller bearing units. The second is their high-efficiency ball bearing with centrifugal disc, a high-performance, friction-optimised and sustainable product for electromobility applications. It aims to combine the benefits of both open-bearing and sealed-bearing designs.
With 0.3 Nm less friction and CO2 emission reductions of about 0.1/km per bearing, this is a smart yet simple solution that has a major impact on overall performance.
