A device for transmitting linear measuring motion comprises a U-shaped element and a T-shaped element, the stem of which is received between the limbs of the U-shaped element. The elements are connected for relative axial displacement and rotational motion by means of a ball bearing. Rotational motion is prevented by an anti-friction bearing between the elements. The elements are biased against each other over the anti-friction bearing accurately guiding the elements for relative axial displacement thereof. |
