Los <strong>rodamientos<\/strong> est\u00e1n muy bien dise\u00f1ados y permiten que el carro se deslice con una suavidad sorprendente.<\/p>\n<p>Los rodamientos funcionan colocando peque\u00f1as bolas entre la rueda y el eje. De este modo, la \u00abfricci\u00f3n por deslizamiento\u00bb, en la que dos superficies se rozan entre s\u00ed, se transforma en \u00abfricci\u00f3n por rodadura\u00bb, en la que las bolas ruedan.<\/p>\n<p>Como la fricci\u00f3n por rodadura es mucho menor que la fricci\u00f3n por deslizamiento, el carro puede aproximarse mucho m\u00e1s a un movimiento ideal, pr\u00e1cticamente sin fricci\u00f3n.
