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.

In an installation channel to be embedded into a curable construction material, e.g. concrete, having a support profile and preferably an attachment for attaching at least one add-on part to the installation channel, so that the outside of the support profile has a direct connection to the curable construction material at an embedding area, a potential fault block should be large so that large forces can be absorbed by the installation channel. A compressible insert is fastened to the outside of the support profile at the embedding area, so that part of the outside of the support profile is not in direct contact with the curable construction material at the embedding area.

A hand-held power tool () includes a linear motor () having a rotor () which is movable along a percussion axis (A) in an axially limited manner between two reversal points (W) and which can be driven by the striking piston () of the power tool with the intermediary of an air spring (), sensors designed for determining the actual state of the rotor () and connected to a computer () connected via power electronics () to at least one field coil () of the linear motor (), with the rotor () being displaced against a contact element () at least at one reversal point (W) and being pressed against the contact element electromagnetically; and a control process for the hand-held power tool.

A clamping device connects two, axially harmonically oscillating components which oscillate, as a result of their respective plane surfaces impacting each other with a frequency &#x3c9; in the form of a stationary longitudinal wave with a distance A between two nodes K. The clamping device includes an axially extending springy gripping yoke having two clamping elements. The two clamping elements are located at opposite ends of the gripping yoke. The two clamping elements are spaced apart from each other by a distance corresponding to the distance A between the two nodes K of the longitudinal wave.
