Abstract: An electric hand tool is disclosed which has a gt (15), received in a housing (10), with a gear shaft (20) and also has at least one radial bearing (30) for rotary support of the gear shaft (20), the inner bearing ring (301) of the radial bearing being fixed on the gear shaft (20) and the outer bearing ring (302) of the radial bearing being fixed in a bearing box (31) disposed in the housing (10), in each case being fixed axially nondisplaceably. For simple assembly of the gt (15) without tools, the outer bearing ring (302) of the radial bearing (30) rests with a sliding seat in the bearing box (31) and is fixed by means of a clamping bracket (32) fixed to the bearing box (31).

Abstract: The invention is based on an electrical machine with a rotatable brush plate (10, 12), which is held in its end positions by means of at least one holding mechanism (16, 18) that acts in the circumference direction (14).

Abstract: A low-wear sealing ring, which assures a favorable sealing action that prevents the escape of lubricants from the transmission chamber of the machine tool and prevents the entry of dust into the transmission chamber, has a number of sealing lips (6, 7) that rest against a percussion bolt (3) in the machine tool. At least on its lateral flank oriented toward the machine, the sealing ring (4) is provided with one or more radially extending recesses (8, 9). This lends the sealing lips (6, 7) a high degree of flexibility, allowing them to easily follow the movements of the percussion bolt (3), as a result of which the sealing ring (4) has a low susceptibility to wear and assures a high degree of impermeability.
