Linear systems for nanopositioning
When we talk about linear motion, we typically discuss applications where the travel distance is at least a few hundred millimeters, and the required positioning is in the range of a few tenths of a millimeter. And for these requirements, guides and drives with recirculating bearings are a good fit. Case in point: the lead […]
