Las recomendaciones de par se calculan suponiendo un coeficiente de fricci\u00f3n de 0,14, que requiere un lubricante de buena calidad. Si la lubricaci\u00f3n es insuficiente, la precarga puede variar considerablemente.<\/p>\n<p>\u00b2 La precarga aplicada kN se calcula como el 65 % de Rp0.2, pero en la pr\u00e1ctica cabe esperar que el valor var\u00ede entre el 50 % y el 80 % (+\/- 23 %).<\/p>\n<p>\u00b3 El nivel de resistencia t\u00edpico de BUMAX\u00ae Ultra, \u00abLa fijaci\u00f3n de acero inoxidable m\u00e1s resistente del mundo\u00bb, es 159 (resistencia a la tracci\u00f3n m\u00edn. 1500 MPa\/ L\u00edmite el\u00e1stico m\u00edn. 1350 MPa).
