Automotive steering components

Customised engineering example

Sometimes the dimensions of a component make force testing difficult to perform. Our client needed to test the sliding force of a bearing along the length of a steering rack. To obtain accurate and repeatable results it required precise axial alignment between the bearing grip and the end of the steering rod.

The test required a test stand with sufficient space to accommodate the steering rack and custom fixtures to hold it.

Mecmesin supplied a twin-column tensile tester and designed the required fixtures for both push and pull testing of the bearing.  Controlled by Emperor data acquisition and analysis software, engineers were then able to assess the smoothness of the bearing movement by measuring the frictional forces over the full distance of its travel,
