ABSTRACT:
A linear motion transfer apparatus has a longitudinally slit elongated tubular structure (1) closed at its ends, in which a force accepting element (4) driven in the axial direction is guided in a longitudinally displaceable manner, and the longitudinal slit (10) of which is sealed off at both ends of the force accepting element by an inner flexible sealing element (27), which is guided underneath a force transfer element (11) protruding to the outside through the longitudinal slit and connected to the force accepting element (11), and with which a flexible covering element (30) is associated. The force transfer element (11) is longitudinally guided, by means of a ball-like guide element (17) partially encompassing the tubular structure (10), on at least two parallel guide tracks (16), which are disposed on both sides of the longitudinal slit (10) directly on the outside of the tubular structure (1). In order to prevent uneven loading, especially of the force accepting element, caused by tolerances, the arrangement is such that the force accepting element (4) is coupled to the guide element (17) at least one bearing (18) in such a manner that limited movement is permitted.
