Abstract
A linear gauging head, for example a “cartridge” head, includes a casing ( ), a spindle ( ), movable with respect to the casing along a longitudinal axis, a feeler ( ′) coupled to a first end of the spindle, and a differential position transducer with windings ( ), stationary with respect to the casing, and a core ( ) coupled to a second end of the spindle. The spindle includes longitudinal grooves ( ) and is guided by means of an axial bearing ( ) with rolling elements ( ) that cooperate with the grooves for allowing the spindle to translate with respect to the casing along the longitudinal axis, and concurrently prevent it from rotating about said axis.
