Motorized Linear Stages

Yes. Translation stage, linear translation stage, linear stage and motorised slide all describe the same machine: a table carried on a guideway and driven along one axis by a screw. Different suppliers print different names on the same product, which is why this page uses more than one.

Both are in this series. Crossed-roller guideways carry the load on rollers in line contact, which gives higher stiffness and lower running error for the same envelope; linear-ball guideways cost less and tolerate more contamination. The guideway of every model is published in its specification table, so you can filter on it rather than infer it from the part number.

A total. The supplied catalogue quotes eleven of the seventeen linear models as a half range — ±7.5 mm — and the other six as a total. The part number always encodes the total. Every travel on this site is published as a total with the source wording shown beside it, so nobody specifies a stage with half the stroke they need.

That there is no position feedback: the controller counts steps and trusts the mechanics, so a missed step under load or acceleration is not detected or corrected. The supplied catalogue also publishes no backlash figure and no minimum incremental motion, and does not state whether its ± repeatability is unidirectional or bidirectional. If a reversing move has to land, ask engineering to confirm those three for the model and the load before you commit.
