<p>The invention relates to a measuring device for precisely determining the length of at least one longitudinal profile between two measuring arms opposite of one another, with said two measuring arms opposite of one another and a measuring stamp, which can be moved in one of the measuring arms by means of a linear guide. The longitudinal profile can be positioned such that one end abuts against the measuring stamp. The linear guide comprises a guide channel extending in a guiding direction and a guide element having an outer wall, which guide element can be moved back and forth in the guide channel along the guiding direction. The guide element comprises a first guide length and a first guide width and forms a first width/length ratio. On the outer wall, in a cross-section that is vertical to the guiding direction, indentations and/or protrusions are provided circumferentially in the guide section direction, each having an additional guide length, an additional guide width and an additional width/length ratio, wherein the additional width/length ratios are smaller than the first width/length ratio.</p> |
