A Roller Bearing is really an extraordinary piece of mechanical engineering. The smallest types have a diameter of no more than a few millimeters and are used in dentist drilling devices with maximum rotation speeds of more than 30.000 rpm, while the largest ones are used in tunnel drilling equipment and measure more than 7 meters in diameter, while rotating at no more than a few rpm's per day.
 
Linked is an article about one of Koyo's mega bearings for such an application.

Koyo is certifying „Waelzlager- & Antriebstechnik“ as new Distributor for Needle Roller Components

The Bodensee based company will be added to the distributor network, starting with the promotion of needle roller components retroactively by Jan 1st 2019.

“Waelzlager- & Antriebstechnik” – shortly named W&A – see themselves as system specialist for all issues that relate to motion- and drive technologies.

W&A´s hybrid function is a diverse split in-between being a wholesaler for rotating applications, but also in the same way problem solving specialists for any kind  of technical applications with consultant expertise.

The Company started already in 2001 as spare part seller for the  mechanical engineering industries.

Being announced as Plus-Partner in the segment of Bearings, W&A and Koyo aim to tighten the network and support their customer activities interregionally.

Koyo handed-over the distributor certificate during the FMB Süd – local supply fair for machine building – in Augsburg, earlier this Year.

Mr. Sven Bäuerle – General Manager of W&A – appreciated the certification as a foundation stone for the future activities of both companies.

WELCOME W&A to the Koyo Distribution Partner network!

FAQ

¿Qué es un rodamiento de Bolas de Contacto Angular?

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.
