robolink® wires were tested for tensile strength on the ZWICK tractor (nominal tensile strength > 3600 N).
The nipple connection was fixed with different adhesives (see installation instructions for the wires). The experiments were carried out at room temperature and at 80°C.
|Wire with brass nipples||Section of the mounted nipple|
|Wire fixed with:||Breaking strength at RT||Breaking strength at 80°C|
|1) Loctite 401||> 1.400 N||> 800 N|
|2) Loctite 406 with primer||> 1.300 N||> 700 N|
|3) Loctite 4204||> 1.900 N||> 1.400 N|
|4) Loctite 4204 with primer||> 1.400 N||> 1.000 N|
igus® recommends the use of Loctite 4204 for installation of the wire nipple, especially because the use of wires/joints results in increased temperatures.
