JTEKT Corporation, the Koyo bearing manufacturer, is recognised as the world's largest bearing supplier to the Automotive OE and Components and has been taking major further steps to increase its presence into the Industrial OE and the Aftermarket business by making technological improvements on the standard radial bearing range.
Today we are proud to announce that Koyo will introduce a new Dynamic load rating (1.25 x C). Since the mid 90's Koyo has been testing manufacturing improvements leading to a clearer comparison between actual and calculated bearing life. These achievements reached thanks to improved daily manufacturing processes and also new steel specifications,allow JTEKT to offer today on the market, the longest service life (2X calculated life).
‘Business and a bit of holiday magic abroad’ …

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.
