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
The price increase for Koyo bearings will be effective as of the 1st of April 2020:
2,9% (flat increase) for all main series

Se trata de un rodamiento de bolas que tiene pistas de rodadura asimétricas. La carga axial atraviesa el rodamiento en una línea recta diagonal, al mismo tiempo la carga radial sigue una línea oblicua. Ambas condiciones provocan la separación axial de las pistas del rodamiento.
El rodamiento de Bolas Contacto Angular tiene una buena capacidad de carga combinada; a medida que el ángulo de contacto es mayor, la capacidad axial aumenta en detrimento de la radial (el ángulo es el mismo para ambas pistas de contacto, interior y exterior); el rango habitual del ángulo es de 10 a 45 grados.
En aplicaciones de alta velocidad, como turbinas o motores a reacción, el ángulo de contacto en las pistas resulta modificado por la fuerza centrífuga generada por las bolas. En estos casos se utilizan bolas de material cerámico por su baja densidad respecto al acero (un 40% de este aprox), por eso estos materiales reducen significativamente la fuerza centrífuga y se comportan bien a altas temperaturas; además de tener un comportamiento mecánico de fallo similar al acero de rodamiento.
Como ejemplo de aplicación, las horquillas de motos o bicicletas usan este tipo de rodamientos por estar sometidos a cargas en ambas direcciones.
