This year’s show puts in spotlight the impressive diversity of suppliers throughout the whole automotive value added chain. IAA is obviously a show JTEKT couldn’t miss.
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.
