Abstract
A linear gauging head, or cartridge head, comprises a casing (1), a spindle (10) movable with respect to the casing along a longitudinal axis, a feeler (12) coupled to a first end of the spindle and a differential position transducer with windings (13, 14, 15), fixed with respect to casing (1), and a core (16) coupled to a second end of spindle (10). The spindle is guided by recirculating ball bushings (18, 19) with rolling elements (29) that cooperate with the spindle and thus allow its displacement with respect to the casing.
