Abstract: The invention concerns a device to hold a motor-driven work spindle (1) in a housing of a processing machine with an outside ring (7) and an inside ring (6), arranged within the outside ring (7), so that it can be displaced and tilted axially, to hold the work spindle (1), wherein the inside ring (6) is pretensioned with respect to the outside ring (7), in an elastically resilient manner in the axial direction, by at least one pretension element (8), and wherein the inside ring (6) is held in an operating position within the outside ring (7) by a holding device with a prespecified holding force. The holding device is designed as a magnet arrangement (9) with at least one magnet (35, 36; 43), arranged in the inside ring (6) and/or the outside ring (7), for the creation of a magnetic holding force.
