Guide Bush N553

Art. no. 5009097

  • Sealing and stop rings fixed on both sides.
  • The closed guide bush and integrated ball cage form a separate component. Guide bore diameter d1 is finely honed to ISO tolerance IT 3, Rz 0.5 – 1.5 μm depending on diameter.
  • Roundness within 1/3 ISO-IT 3.
  • Cylindricity within IT 1.
  • Radial run-out of a shaft inserted under preloading is within 0.0005 mm.
  • Outside diameter dB n4 with radial run-out error within IT 4, ground to guide bore diameter d1, lead-in taper on one side.
  • The maximum stroke path Hmax of the rotary stroke bearing is determined from the length of guide bush l3 and the length of the ball cage l2: Hmax = 2 (l3-l2).
  • See catalog page 37-41 for instructions on installation and servicing.

Einpressen vermeiden!

Durch Einpressen wird der mit sehr hoher Genauigkeit gefertigte Führungsdurchmesser d1 verformt. Die Buchse passt sich der Aufnahmebohrung an. Formfehler und erhöhte Vorspannung sind die Folge. Die Funktion der Kugelführung wird auf jeden Fall negativ beeinflusst.

Die Kugeleingriffsstrecken werden von der gegenseitigen Lage von Führungsbuchse, Kugelkäfig und Führungswelle in der Hubendstellung bestimmt. Das Zusammenspiel der Baulängen l1 und l2 während der Bewegungsabläufe über den Hub bedingt unterschiedliche Betriebsarten.
