 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.

FAQ

Ce este un rulment cu contact unghiular?

Un rulment cu contact unghiular are căile de rulare axial asimetrice. O sarcină axială trece într-o linie dreaptă prin lagăr, în timp ce o sarcină radială are un traseu oblic, a cărei rezultanta tinde să se separe căile de rulare pe direcție axiala. Unghiul de contact de pe inelul interior este același cu cel pe inelul exterior. Rulmenții cu contact unghiulari suporta mai bine „încărcări le combinate" (încărcări în ambele direcții, radiala si axiala) și unghiul de contact al rulmentului trebuie să fie adaptat la proporția relativa a fiecărei forte. Cu cat unghiul de contact este mai mare (de obicei, în intervalul 10 - 45 de grade), cu atât mai mare este capacitatea de încărcare axială, dar mai mică cea radială. În aplicații de mare viteză, cum ar fi turbinele, motoare si echipamente cu jet, echipamente pentru stomatologie, forțele centrifuge generate de bile schimbă unghiul de contact de la inelul interior și exterior. Materialele ceramice, cum ar fi nitrura de siliciu sunt acum utilizate cu regularitate în astfel de aplicații, datorită densității lor scăzute (40% din cea a oțelului). Aceste materiale reduc semnificativ forța centrifugă și funcționează bine în medii cu temperaturi ridicate. Ele au, de asemenea, un comportament la uzura similar cu cel al oțelului, nu se crapă sau se sparg ca sticla sau porțelanul.

Cele mai multe biciclete utilizează rulmenți cu contact unghiular - in furca, deoarece forțele de pe aceste lagăre sunt atât de direcție radială cat și axială.
