JTEKT has recently introduced the ONI bearing for application in race bicycle wheels. The ceramic Oni bearing provides superior performance by reducing internal friction to the absolute minimum without compromising strength and durability.
To emphasize our target to promote this bearing for high level professional cyclists we are advertising (page 113) in the French magazine Le Cycle (Special Tour De France edition)

JTEKT has recently introduced the ONI bearing for application in race bicycle wheels. The ceramic Oni bearing provides superior performance by reducing internal friction to the absolute minimum without compromising strength and durability.
At the same time JTEKT supports initiatives to train “wannabe” future bicycle racers, to participate safely to the daily traffic on the road.
“.....before you can reach the professional top with JTEKT ONI race wheel bearings, you need to start at an early age to learn to participate safely to the road traffic: this is exactly what J&L Verlag is doing by providing training to children in several German communities and JTEKT is happy to sponsor this great initiative.....” says Selma Baruch, Marketing Specialist at JTEKT Europe Bearings.

JTEKT Europe Bearings B.V. (formerly Koyo Europe) will be participating at Hannover Messe 2023 with a small booth in the Motion+Drive pavilion in hall 5, booth D04/2. This will be an excellent opportunity to meet & greet “live” after several years of (too many) online meetings. We will be featuring several new products including the race bicycle ONI-bearing, the ultra-compact JUCB-bearing and the JTEKT Lithium Ion Capacitor. This will also be an excellent opportunity to promote the brand-transition from Koyo to JTEKT.
The recently introduced ONI bearings, using ceramic balls and a special internal design to secure ultra low friction while maintaining bearing durability, are now becoming more popular among participants of the JAPAN PRO TOUR races.
The MATRIX POWERTAG Team is testifying about the performance of these professional speed cycle race wheel bearings:

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.
