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

Se trata de rodamientos formados por rodillos con geometría tronco cónica, ubicados entre los dos anillos (con sus pistas de rodadura), el interior, también denominado cono, y el exterior, también denominado aro. Los rodillos están guiados por una jaula y la pestaña guía del anillo interior.
Posee gran capacidad de carga combinada, radial y axial simultáneamente, a velocidades bajas e intermedias. Su configuración puede ser de una, dos o cuatro hileras. Los rodamientos cónicos de una hilera pueden soportar cargas axiales de hasta un 60% del valor de la carga radial, dependiendo del ángulo de contacto. Los de doble hilera tienen gran capacidad de carga radial y pueden soportar cargas axiales en ambas direcciones. La disposición de las hileras, y orientación de los rodillos, en estos rodamientos dobles pueden ser divergentes o convergentes al eje de rotación. En el primer caso se consigue mayor rigidez y en el segundo absorber mayores desalineaciones. Según sus componentes, se encuentran rodamientos de doble hilera con un solo cono y dos aros o dos conos y un solo aro. Los rodamientos de cuatro hileras alternan hileras de rodillos convergentes y divergentes.
