Introducción de los rodamientos de bolas de contacto angular de una hilera:
Los rodamientos de bolas de contacto angular de una hilera solo pueden soportar cargas axiales en una dirección.
Debido a que la línea de acción de la carga del elemento rodante y la línea de acción de la carga radial no están en el mismo plano radial, se genera una componente de fuerza axial interna.
Como resultado, los rodamientos de bolas de contacto angular de una hilera deben instalarse en pares.
Los rodamientos de bolas de contacto angular de una hilera están diseñados para aplicaciones de alta demanda, alta velocidad y alta precisión.
Los cojinetes de husillo dispuestos en pares "espalda con espalda" o "cara a cara" pueden soportar fuerzas axiales en dos direcciones y momentos.
Los rodamientos dispuestos en serie solo pueden soportar cargas axiales en una dirección.
Los cojinetes del husillo pueden proporcionar un ángulo de contacto de 15 grados o 25 grados y 30 grados.
Podemos fabricar jaulas de diversos materiales y rodamientos de bolas de cerámica a medida para una mayor demanda de velocidad de giro.
