A screw drive includes a spindle and a nut with a nut body. The nut body has at least one hole for a fastening member that is configured to enable the screw drive to be fastened on a higher-level subassembly or on a higher-level construction component. The at least one hole is further configured as a coolant duct of a coolant path. In one embodiment, an interior space between the nut body and the spindle is configured as a coolant duct.

A guide carriage includes a main body, a separate track element connected to the main body, at least one carriage track, at least one deformation sensor, an evaluating device, and at least one row of endlessly revolving roller elements that roll off on an associated carriage track in a load-transmitting manner. The carriage track extends parallel to a longitudinal axis, and is positioned on the track element. The track element has at least one self-supporting section not supported on the main body and located at one end of the track element along the direction of the longitudinal axis. The at least one deformation sensor is connected to the evaluating device, positioned in a region of a respective self-supporting section of the track element, and configured to measure a deformation of the respective one of the at least one self-supporting sections of the track element.

A guide carriage is configured for use with an elongate guide rail. The guide carriage has at least one row of spherical rolling bodies which are received in an associated endless circulatory channel. The circulatory channel has a load-bearing section and a return channel which are connected to one another at their ends which lie opposite one another via in each case one curved deflection channel. The load-bearing section is delimited by a carriage raceway extending in a longitudinal direction on the guide carriage and a rail raceway on the guide rail. A separate main body of metal is also provided. The carriage raceway is arranged on a separate raceway insert which bears against the main body. A separate rolling-body guide part is also provided which has a guide section extending in the longitudinal direction. The guide section engages behind the raceway insert.
