Abstract

Mejoras introducidas en las monturas de cojinete que comprende miembros interior y exterior relativamente giratorios un cojinete de antifricción giratorio radial y de empuje interpuesto entre los miembros y un manguito de montura para el cojinete con una porción sostenida directamente por uno de los miembros y otra anteriormente libre de ellos que sostiene el cojinete siendo esta última porción mencionada extensible radialmente para adaptarse a la dilatación diametral de cojinete debida a los aumentos de temperatura en el funcionamiento del mismo a gran velocidad.
