JTEKT is dedicated to providing products and services to assist in the maintenance of JTEKT products so that they can be used safely and continuously by customers. One such product we are proud to introduce is our Bearing Defender portable status monitoring device.

The Bearing Defender portable status monitoring device detects bearing failures to ensure customer operations remain stable.

Routinely monitoring the status of bearings enables customers to purchase replacements in advance for bearings that are likely to break and to develop optimized maintenance plans, contributing to improved productivity.

JTEKT Bearings (formerly known as Koyo Bearings) is gradually expanding its business activities from OEM markets to the MRO (Maintenance Repair and Overhaul) market via distributors. Recently a move closer to the "final user" was made with the introduction of the ONI wheel bearing for the (semi)professional bicycle race market. The ONI bearing that features extremely low friction combined with superior durability, was tested during the Amsterdam triathlon race in September 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.

JTEKT Bearings (formerly Koyo Bearings) is a global manufacturer and supplier of highly engineered bearings for a large diversity of demanding industrial applications including Agricultural & Construction machines. In these industries products must meet the strictest specifications related to robustness, reliability and durability. Increasingly low friction is becoming important to reduce energy consumption, especially considering ongoing electrification.

To get an impression about these applications and the types of JTEKT bearings involved, here is a link to a Youtube video related to such products:

FAQ

Was ist ein Schrägkugellager?

Ein Schrägkugellager nutzt axialsymmetrische Kugelschalen. Eine Axialbelastung verläuft in einer geraden Linie durch das Lager, wohingegen eine Radialbelastung einen schräg verlaufenden Weg nimmt, der die Kugelschalen axial separieren möchte. Daher ist der Kontaktwinkel an der inneren Kugelschale identisch mit dem Kontaktwinkel an der äußeren Kugelschale. Schrägkugellager unterstützen „kombinierte Belastungen“ besser (Belastungen sowohl in der radialen als auch axialen Richtung). Der Kontaktwinkel des Lagers sollte dabei an die relativen Proportionen jeder dieser Belastungen angepasst werden. Je größer der Kontaktwinkel (normalerweise im Bereich zwischen 10 und 45 Grad), desto höher die aufnehmbare axiale Last, aber desto geringer die radiale Last. Bei Hochgeschwindigkeitsanwendungen wie Turbinen, Flugzeugtriebwerken und zahntechnischen Geräten ändern die von den Kugeln erzeugten Zentrifugalkräfte den Kontaktwinkel an der inneren und äußeren Kugelschale. Keramiken wie Siliziumnitrid werden heutzutage aufgrund ihrer geringen Dichte (40% Stahlanteil) regelmäßig für solche Anwendungen eingesetzt. Diese Materialen reduzieren die Zentrifugalkraft erheblich und funktionieren gut bei hohen Temperaturen. Sie tendieren aber auch dazu, ähnlich wie Lagerstahl zu verschleißen, anstatt wie Glas oder Porzellan zu zerbrechen oder zu zerspringen.

Bei den meisten Fahrrädern werden Schrägkugellager in den Lenkköpfen eingesetzt, da die Kräfte auf diese Lager sowohl in der radialen als auch in der axialen Richtung wirken.
