Abstract
A power chuck includes a housing in which there is arranged a drive unit having a traction guide means moveable in the direction of a clamping axis. There are arranged two pairs of mutually diametrically opposite base jaws. The base jaws are guided radially, in the housing substantially perpendicularly to the clamping axis, and the drive unit is adapted to convert the movement of the traction guide means into the movement of the base jaws. According to the invention, it is proposed that the drive unit for each base jaw has a slider which is in engagement with the base jaw and which is moveable with a movement component on a circular path about the clamping axis.
