Abstract:
A linear drive comprisinga displaceable component and a housing for a driving means which cooperates with the displaceable component and rotates about a common axle of the displaceable component and the housing;a bearing device supporting the driving means in the housing, with at least one first bearing component supported on the driving means, and at least one second bearing component (6) supported on the housing, in the form of a bearing ring;a device comprising a force sensor (7) for detecting and evaluating a driving force acting on the linear drive; said force sensor (7) is axially clamped between the at least one bearing ring (6) and the housing (5); the axially clamped force sensor (7) is supported between support surfaces of the at least one bearing ring and the housing (5), said surfaces axially opposing each other; andthe at least one second bearing component is essentially non-rotatable longitudinally displaceable with respect to the housing (5).
