Dovetail
Dovetail slides are the simplest type of linear translation stage. They consist of two flat surfaces sliding against each other. Dovetail slides can provide long travel and have relatively high stiffness and load capacity. They are more resistant to shock than other bearings and reasonably immune to contamination, but their friction varies with translation speed. This friction makes precision control difficult and limits the resolution of the stage. Dovetail stages are manually driven devices that work well in vacuum or nonmagnetic applications.
