Abstract
A spindle for a spinning or twisting machine includes a step bearing sleeve which is supported in a damping tube. The damping tube is arranged, with clearance from an oil filled damping gap, free floating and radially movable in a bearing housing. The damping gap has preferably a gap width of 0.2 mm to 0.4 mm. The damping tube is provided with radial bore holes, which connect the damping gap with the area of the step bearing sleeve. In spite of even the smallest radial movements of the damping tube, a hydraulic damping as well as a hydraulic centering is possible.
