Rotierbare

Rotierbare is the attributive form of the German adjective rotierbar, meaning capable of rotation or rotatable. It is used to describe objects, components, or mechanisms that can rotate around an axis, whether freely or within defined limits. The term is common in technical contexts such as mechanical design, engineering specifications, optics, and robotics.

In German grammar, rotierbar inflects like other adjectives. The form rotierbare appears in feminine singular and neuter singular when used with a definite article: die rotierbare Achse (the rotatable axis), das rotierbare Teil (the rotatable part). With an indefinite article or without an article, different endings apply: ein rotierbares Teil (a rotatable part) and die rotierbaren Teile (the rotatable parts). The masculine singular would be der rotierbare Knopf, and the plural with definite article is die rotierbaren Teile.

Common contexts and examples include rotierbare Achsen, rotierbare Gelenke, rotierbare Komponenten, and rotierbare Montagesysteme. Such descriptions are important for specifying bearing loads, torque, backlash, and range of motion. In practice, the term is often preferred in technical writing, while drehbar is a more everyday synonym used in less formal language.

Notes and distinctions: rotierbar is a precise technical descriptor, whereas drehbar is widespread in everyday German. Both convey rotation capability, but rotierbar signals a formal or engineering-focused usage. The noun forms are not standard; rotierbar/rotierbare serves as an adjective, describing the relevant noun.
