New bearing solutions for e-mobility from Schaeffler

Schaeffler, one of the world’s leading suppliers to the automotive and industrial sectors, develops bearings for electric mobility to strengthen the bearing field. Schaeffler’s innovative bearing technologies are essential for efficient and sustainable mobility. The company’s innovative new products, the TriFinity three-row bearing and high-efficiency ball bearing with centrifugal disc, provide superior efficiency and life for all types of powertrains. These new special bearing solutions designed by Schaeffler for electric vehicles underline the successful transformation of the company.

Innovative bearing solutions play a key role in sustainable mobility by making powertrains and chassis systems more efficient. Thus, the energy saved in electric vehicles provides a longer range. That’s why vehicle developers are looking closely at the field of bearings to optimize friction performance and increase service life for customers. Recognizing the potential impact of innovative bearings, global automotive and industrial supplier Schaeffler has also launched two innovative new products specifically designed for electric vehicles, the TriFinity three-row wheel bearing and ball bearing high efficiency centrifugal disc. Matthias Zink, CEO of Schaeffler AG Automotive Technologies, said that innovative bearing technologies are an essential part of their product DNA and are the basis of the success of the Automotive Technologies units. He seeks to integrate efficient and high-precision bearing solutions into these systems to make them durable. noted.

Together with its customers, it aims to take bearings to a new level

Schaeffler created a new Bearings business unit within its Automotive Technologies division earlier this year to increase synergies and shorten development times for its special solutions. Dieter Eireiner, Director of the Bearings Business Unit of the Schaeffler Automotive Technologies Division, said: “E-mobility is a huge opportunity in the field of bearings. As a company, we expect strong growth over the next few years, with significant sales potential, especially in ball, cylindrical roller and taper roller bearings. We are already involved in many promising development projects involving renowned car manufacturers. Innovative bearing technologies are also very important for light commercial vehicles and heavy-duty vehicles. Because it considerably increases the range of vehicles. By working with our customers, we aim to take bearings to a new level. he said.

TriFinity: three-row bearing for maximum modularity

Schaeffler’s TriFinity product stands out as a three-row wheel bearing designed for use in electric powertrains. TriFinity is the size of standard double row ball bearings and can transfer larger axle loads. It also provides longer life and better stability compared to other bearings. This innovative ball bearing design provides an alternative to preloaded tapered roller bearings. Changing from tapered rollers to ball bearings provides significant improvements in frictional torque and stability, resulting in a 75% reduction in electricity consumption per vehicle in FTP0.7 test cycles. The combination of TriFinity with Schaeffler’s face mill technology enables reduction solutions in the form of smaller diameter wheel bearing units, resulting in reduced bearing and seal friction, bearing weight optimized and a reduced carbon footprint. Clearance-free facing technology applied in the same dimensions reduces bearing weight and allows the component to transmit up to 50% more drive torque. It also simplifies bearing assembly and reduces noise emissions from electric vehicles.

High performance ball bearing for high efficiency and maximum life

Schaeffler’s new high-efficiency ball bearing with centrifugal disc stands out as a durable, high-performance, friction-optimized product for electromobility applications. This product combines the advantages of open bearing and sealed bearing designs. The high-efficiency ball bearing with centrifugal disc, which provides 0.3 Nm less friction and approximately 0.1/km reduction in CO2 emissions for each bearing, stands out as a smart and very simple solution that has a significant impact on overall performance. With ten times the service life of an open bearing, these bearings also significantly reduce costs. With all these features and innovative structure, Magna Supplier Award kazan Deep Groove Ball Bearing was also nominated for 2022 Innovation Award in Germany.
