Spring-Loaded Grips

These grips are particularly suitable for tests involving very low forces. Their weight is sufficiently low in relation to the nominal force of the attached load cell as to impose no restrictions on the force measurement range of the load cell. The gripping force is generated by a spring. The spring force can be preset, allowing clamping-sensitive materials always to be tested using the same gripping force.

Spring-Loaded Grips

Fmax 20 N

  • The specimen grip is equipped with a centering ring for clamping threads or wires
  • The jaws can be tilted and precisely adjusted to the specimen
  • The specimen grips ensure a consistent gripping force
  • Lightweight and well suited for load cells designed for small nominal forces
  • Inserting the specimen is fast and easy

Applications

  • Specimen material:
    Ferrous and non-ferrous metals, paper, plastics, insulating materials, artificial leather
  • Specimen shape:
    Round specimens, strip specimens, flat specimens (foils) with or without reinforced gripping ends (dumbbells)
  • Type of loading:
    Tensile
