Please be informed that Koyo Bearings will be rebranding to JTEKT Bearings as of April 1, 2022. For your information, this is only a change of brand. The company, its general structure, the products and services will remain the same. Our customers can rely on the continued good service and quality of our products in the future and our commitment to keep the same excellent business relationships with our valued partners, as in the past.
Please take note that although the official date for this corporate brand change will be April 1, 2022, the actual introduction of the new JTEKT branded products and the phase out of the Koyo brand will be subject to a gradual process, far beyond this date. We expect that the full transition will practically take at least 2-3 years.

What is the relation between a covid virus and a roller bearing? Well, strictly there is no relation, at least not directly . .
But surely to identify the covid virus, a massive amount of PCR tests needs to be done globally, every day. And to process all those tests quickly, increasingly automated laboratories are installed in many countries. Those laboratories need quick, smooth and reliable handling of the test materials. And here is where roller bearings come into play.
In the below linked article you can see how Koyo bearings (note: as of April 1, “Koyo” will be rebranded to “JTEKT”) are contributing with state-of-the-art bearings for such automated laboratories.

KOYO & ROYSE teamed up for a distribution partnership on the Spain territory since 2019. The partnership was clearly in both parties interest.
First, it is granting KOYO a stronger presence on the Iberian Peninsula thanks ROYSE ‘s 12 agencies spreading all accross Spain.
Then, ROYSE is given the opportunity to offer to his Market KOYO’s high quality, durable products coming along with manufacturing expetise and precision engineering capabilities.
As KOYO’s always wanting his Partners to be more knowledgeable and engaged with his products, an e-learning session dedicated to ROYSE Sales Force has taken place on 14th September. The session was gathering not less than 20 Sales Managers from ROYSE for a 2 hours training.
Several subjects were covered such as Brand history, Group activities but also product range and other specifics in order to increase ROYSE ‘s Team Brand awareness and enhance more trust in Koyo Products and manufacturing facilities. Main objective was to create real « KOYO’s Brand Promoters » by giving them the needed information for Professional arguments by selling Koyo.
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.
