Abstract
A hand-held power tool, for example a rotary percussive drill, includes a component for undergoing linear movement and a bearing support for the component. The bearing support comprises a cylinder formed from sheet metal strip with the longitudinal edges spaced to form a gap in the wall of the cylinder. By making the bearing support from a sheet metal strip and providing a gap in the cylinder wall considerable cost savings are achieved.
