Abstract: The invention relates to a bearing housing for driven and air-suspended spinning rings on ring-spinning and ring-twisting machines, whereby a tape drive with tensioning pulleys is provided for the spinning rings. The object of the invention is to decrease the amount of material and working time when the bearing housings are attached (applied) to the ring rail and to shorten the time required for the adjustment of the spinning rings and of the tensioning pulleys. The technical task which is being solved by the invention is constituted by the fact that the number of fastening elements needed for the attachment of the bearing housings to the ring rail is decreased and that the spinning rings are not individually adjusted and that the tensioning pulleys are not adjusted at all. According to the invention, this is accomplished by having at least two spinning rings (2;3) and one tensioning pulley (5) arranged on one bearing housing (1).
