DIN 9845 Guide Bushings

DIN 9845 guide bushings are high-quality, precision-engineered machine elements offered by Elesa+Ganter. Primarily used in machine tools and punching tools, these bushings ensure accurate guidance of tool components, delivering optimal performance and extended service life.

Main Features

• Type: C type (without flange)

• Material: Hardened steel (ST)

  • Hardness: HRC 62 ±2

  • The mating surfaces d₁ and d₂ are ground

• Tolerances:

  • Inner bore (d₁): H7 tolerance

  • Outer diameter (d₂): n6 tolerance

  • This combination provides a favorable transition fit

• Size Range:

  • Bore diameter (d₁): 2 mm – 16 mm

  • Length (l): 12 mm – 36 mm

  • Outer diameter (d₂): 6 mm – 30 mm

• RoHS Compliance: Yes, compliant with EU Directive 2011/65/EU

Application Recommendations

DIN 9845 guide bushings provide accurate and wear-resistant guidance for tooling components due to their tight dimensional and positional tolerances as well as hardened and finely machined surfaces.
They are recommended for installation in H7 tolerance bores, resulting in an optimal transition fit with the n6 tolerance outer diameter of the bushing.

This makes them universally applicable for various precision engineering and tooling applications.ós gépészeti és szerszámkészítési feladatban.
