JTEKT participates to Cti Berlin symposium (Dec 5-6, 2023)

"Keeping pace during the transformation towards electric mobility"

Cti Berlin symposium
The CTI Symposium brings together experts and decision-makers from passenger car and commercial vehicle OEMs, system and component suppliers, engineering service providers, software developers and market specialists to provide you with the latest developments, innovations and ideas, valuable suggestions and new contacts.

Today’s challenges
The automotive industry is rapidly moving towards zero-emission mobility, which is possible with a variety of drive systems and primary energy sources. Although the industry has gained valuable experience in the mass production of low-emission vehicles, the key question remains: What solutions will enable the necessary transition to carbon-neutral powertrains across all segments and markets, and who are the right business partners to achieve these goals?

JTEKT’s role
JTEKT is developing several technologies that strongly contribute to the future of zero-emission mobility, including advanced steering systems (steer-by-wire, a. o.), compact and low weight drive train systems (ultra compact differentials, a.o.) and rolling bearings (ultra compact bearings, a. o.). These new technologies are currently being developed, tested and validated together with major OEM carmakers.

JTEKT’s displays
If you happen to be visiting the Cti symposium, please join us on our small JTEKT booth (A-8) to see some of our products, discuss and exchange about such new technologies and to see where we can work together in the future.

FAQ

What is an angular contact ball bearing?

An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such as silicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear in a similar way to bearing steel—rather than cracking or shattering like glass or porcelain.

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.
