Koyo introduces new JHS-3i Pillow Blocks

Koyo, the bearing brand of JTEKT Corporation, is introducing its new range of “JHS-3i” high performance Pillow Blocks.

With a legacy of Quality and Performance, Koyo Ball Bearing Units have been known to be the most reliable products when it comes to accuracy and load resistance. The new generation of JHS-3i Pillow Blocks introduces further enhancements in the performance through improvements in the housing, sealing and the applied grease.

The first improvement is realized in the housing design which now has a flat bottom face which secures a more accurate and firm mounting of the pillow block on the frame, resulting in better rigidity and the elimination of vibrations.

The second improvement is realized through an improved seal design with an inwards facing lip which allows grease to flow back towards the balls and raceway during operation, thereby improving lubrication performance and extending bearing life.

The third improvement is in the newly applied high quality Lithium Complex grease providing several improvements, including a wider allowable temperature and speed range, resistance against water contamination, vibration and high pressure, as well as heavy- & shock loads. To summarize: the Koyo JHS-3i Pillow Blocks provide a better performance and longer bearing life under a variety of high demanding operating conditions. Play the best jogos games of Mario, Winx, race, guns. The most popular collection of jogos friv games are presented on this mega portal.

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.
