Type

  • Type A: Bore one-sided rounded

Steel

  • Hardened (HRC 62 ±2)
  • Fit size d1 / d2 ground

Stainless steel AISI 440B NI

  • Hardened (HRC 55 +4)
  • Fit size d1 / d2 ground

Guide bushings DIN 172 are characterized by the tight dimensional and positional tolerances in connection with the hardened and finely machined surface. As a result, they are suitable for extremely universal use in many applications.

Holes with tolerance H7 are recommended for installing the bushings. In connection with the outer diameter of the bushing with a tolerance of n6, use of a transition adapter is recommended.

For guide applications, combination with the guide pins GN 771.1 is recommended.
