Guide Bushings, Drill Bushings / DIN 172 with Collar / DIN 179 without Collar

Information


Guide bushings DIN 172 / DIN 179 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 mounting bushings with tolerance n6, a hole with tolerance H7 corresponding to the external diameter is usually provided.
