The hollow spindle for a textile machine has a spindle attachment to hold the bobbin, fitted to the powered spindle shaft (3) with a force fit. Two roller bearings are in a bearing sleeve (7), which is in a double-tube structure with both tube sections (9,10) firmly bonded together at the bottom to form a sleeve-shaped hollow zone (11). The upper end (13) of the inner tube section (10) has the upper spindle bearing (14), and the lower end (19) of the double-tube structure has the lower spindle bearing (20). The hollow sleeve-shaped interior zone (11) of the double-tube structure is filled with a high viscose damping material, or the hollow zone (11) is in a damping coil of damping oil. The damping medium is air. The tube sections (9,10) are of different materials.
