The invention relates to a power chuck (1), comprising a housing (3) that is equipped with a drive unit (9), which comprises a traction guide element (13) that can be moved in the direction of a clamping axis (S), and two pairs of diametrically opposed base jaws (7a, c; 7b, d). The base jaws (7a-d) are guided in the housing in a movable manner substantially perpendicularly to the clamping axis (S), preferably in a radial manner, and the drive unit (9) is designed to convert the movement of the traction guide element (13) into the movement of the base jaws (7a-d). According to the invention, the drive unit (9) has a slide (15a-d) for each base jaw (7a-d), said slide being in engagement with the base jaw and being movable about the clamping axis with a movement component on a circular track (K). |
