  • Patent number: 10511216
    Abstract: A sliding linear bearing includes a guide shaft on which a slider is movably guided in a guide direction. Bushes are inserted between the guide shaft and the slider including a main bush that is fixedly attached to the slider and a preloading bush that is held so as to be rotatable relative to the slider about the guide direction while being preloaded with a torque. The main bush and the preloading bush are preloaded by the torque in opposite directions of rotation without play relative to the guide shaft. A contact region between each of the bushes and the guide shaft blocks rotation about the guide direction between the slider and the guide shaft in both directions of rotation.
