A roller bearing design is never "final". Even after installation into a machine or device, it may behave differently than expected based on earlier tests, calculations and simulations. Therefore constant engineering support to users is a must for a top bearing manufacturer. Here is an interesting case study .

After the merger of Koyo Seiko and Toyoda Machine Works in 2006 to form JTEKT Corporation, engineers from both divisions have worked closely together to develop state of the art spindle shaft support bearings, which are key to modern machine tools with high accuracy & precision requirements.

Avoiding "bearing creep" is an underestimated challenge when designing the proper roller bearing for certain applications. Bearing creep happens when the outer rings moves relative to the housing in which it is mounted. Simply applying a light press fit seems easier than it practically is and may cause other functional problems. Therefore Koyo has been developing more suitable anti-creep solutions which are described in our latest article in BearingNews:

On February 5-6 Koyo participated with a representative booth at Ditzinger’s DITEC fair in Braunschweig. This was an excellent opportunity to meet with industry representatives, students and experts and the Ditzinger team focussing on MRO (Maintenance, Repair & Overhaul) requirements for all types of manufacturing industries in Northern Germany and other regions. The cut-open Audi DL382-7Q transmission, which includes several Koyo bearings and a JTEKT/Torsen LSD (Limited Slip Differential) attracted a lot of attention. Любая девушка может снять красивый секс

Ein Kegelrollenlager ist ein Lager, in dem Kegelrollen (stumpfe, kegelförmige Rollen) zwischen der Vertiefung (äußerer Ring) und dem Kegel (innerer Ring) eingesetzt sind. Die Rollen werden durch das Führungsbord geführt.
Diese Rollen sind bei niedrigen bis mittleren Drehzahlen radial und axial hochbelastbar. Kegelrollenlager sind in ein-, zwei- und vierreihigen Varianten erhältlich. Bei einreihigen Lagern liegt die Axialbelastung bei ungefähr 60% der radialen Belastbarkeit. Zweireihige Lager weisen eine größere radiale Belastbarkeit auf und können axiale Belastungen aus beiden Richtungen handhaben. Die Rollen können so konfiguriert werden, dass die Kontaktlinien zu den Kugelschalen in Richtung der Drehachse zusammen- oder auseinanderlaufen. Auseinanderlaufende zweireihige Lager erhöhen die Rigidität des Wellenstrangs, zusammenlaufende Lager tun dies hingegen nicht. Weitere Konfigurationen für zweireihige Lager umfassen ein einzelnen Außenring und zwei Innenringe oder zwei Außenringe und einen einzelnen Innenring. Vierreihige Kegelrollenlager bestehen aus vier Reihen abwechselnd angeordneter zusammen- und auseinanderlaufender Rollen.
