Abstract: A linear unit having a main module unit and a drive unit in which the main module unit has a housing with a table part that a drive belt is able to move in the longitudinal direction; the drive belt is wound around a drive roller, which is connected to a drive unit, and around a freewheeling roller; and the drive belt is connected to the table part and is divided into an upper span and a lower span, and a guide element is situated on the base leg of the housing and is able to separate the upper span from the lower span.

Abstract: A linear guide device has a guide rail system with at least one guide rail, a guide carriage guided on the guide rail system in a guidance direction and including a base unit and legs which partially enclose the guide rail system, the guide carriage being provided with at least one preload-adjustment device via which a preload of the legs of guide carriage against the guide rail system is adjustable, the preload-adjustment device including at least one rod having one end hingedly mounted on one of the legs of the guide carriage and the other end displaceable in a displacement direction, and a displacement device for displacing the other end of the preload adjustment, device in the displacement direction.

Abstract: A linear unit has a drive unit, a stator, a drive roller connected to the drive unit, a freewheeling roller supported on the stator adjacent to one of longitudinal ends of the stator, the drive belt being wound around the drive roller and around the freewheeling roller, a traveler movable along the stator by the drive belt, the drive belt being connected to the traveler in at least one fastening point, so that a distance between an end of the traveler which is oriented toward an end of the stator associated with the freewheeling roller, and the fastening point situated the closest to the end of the traveler is at least equal to a radius of the freewheeling roller.

Abstract: A movable bearing for supporting a free end of a threaded spindle of a screw drive, which spindle extends in the direction of a longitudinal axis, has a bearing bush that is accommodated in a bearing housing. The bearing bush has at least one projection protruding outward in the radial direction, which engages in an associated recess of the bearing housing.
