Rodamiento de rodillos cilíndricos de doble hilera
Hay dos tipos de estructuras de rodamientos de rodillos cilíndricos de dos hileras: agujero interno cilíndrico y agujero interno cónico. Este tipo de rodamiento tiene las ventajas de una estructura compacta, alta rigidez, gran capacidad de carga y pequeña deformación después de la carga, etc. Es especialmente adecuado para el soporte del husillo de la máquina. Se puede dividir en dos tipos: series NN y series NNU. El rodamiento de rodillos cilíndricos de la serie NN tiene doble pestaña en el anillo interior, pero no tiene pestaña en el anillo exterior. El rodamiento de tipo NNU tiene doble brida en el anillo exterior pero sin brida en el anillo interior. Ambos rodamientos no limitan el desplazamiento axial relativo entre el eje y la carcasa y pueden utilizarse como rodamientos sin posicionamiento.
