Abstract: A galvanometer drive with a rotor that is rotatable about an axis of rotation and includes a magnet, and a stator unit that surrounds the rotor and includes a coil, the rotor being supported by two bearings, at least one of which is a floating bearing, such that the rotor can perform a rotational movement relative to the stator unit about the axis of rotation. A radial movement limiting device is adapted to limit the radial movement of the floating bearing with respect to the stator unit.

Abstract: The present invention relates to a pre-assembled unit having two tapered roller bearings, for a driven shaft designed to be replaced efficiently and to maintain optimal tightness as if it were factory assembled. The bearing comprises a rubber seal attached to the lateral face of the inner race of one of the tapered rollers, said face being opposite the smooth face of the other tapered roller. The necessary widening of the inner races requires a second invention, namely, a roller cage that allows the rollers to rock slightly in order to be assembled without causing damage or becoming damaged.

Abstract: An exhaust turbocharger including a modular bearing designed for bearing a shaft and arranged between a compressor and a turbine is provided herein. The bearing has a bearing housing having a receptacle chamber, wherein a bearing assembly module can be or is installed in the receptacle chamber and can be non-destructively removed. The receptacle chamber is sized such that either a bearing assembly module having a rolling bearing or a bearing assembly module having a slide bearing can be installed. The receptacle chamber has an interface, designed to contact the bearing flange of a bearing assembly module inserted into the receptacle chamber. The interface is designed to connect an oil gallery passing through the bearing housing to one or more oil galleries passing through a bearing flange of the bearing assembly module.

Abstract: A medical, motor-operated or hand-operated or operable instrument includes a number of bearings for supporting a shaft for applying torque to a tool, of which bearings at least two selected or selectable bearings form a bearing pair. A distance sleeve axially spaces apart the bearings of the bearing pair. The instrument includes a component located at least partly radially inside the distance sleeve. The component is or can be rotationally coupled to at least one of the two bearings to rotate together with a rotating part of the at least one of the two bearings, or to form a rotating part of the at least one of the two bearings. At least one permanent magnet is fastened or formed on or in the component. A coil is arranged on or in the distance sleeve.
