Abstract
A hand-held power tool is disclosed. The power tool has a linear motor with a rotor, an exciter piston that is coupled mechanically to the rotor, and a bearing device with a rotor mounting to support the longitudinal movement of the rotor and an exciter piston mounting to support the exciter piston. The rotor mounting and the exciter piston mounting form a three-point mounting, which is the sole bearing for the rotor and the exciter piston.
