摘要:
A fluid power linear drive device comprises a housing tube on whose outer periphery an output drive slide can slide linearly. For this purpose on the outer periphery of the housing tube there are two guide face pairs each having two guide faces extending along the housing tube on the outer periphery of the housing and, in the axial is direction of a first transverse axis of the housing tube, opposite each other, which in the direction of a second transverse axis, perpendicular to the first transverse axis, are spaced apart. The guide faces, as considered in a cross section of the housing tube, are slanted in each case in relation to the first and second transverse axis, first bearing elements arranged on the output drive slide are engaging the guide faces of the one, first guide face pair, such first bearing elements being able to pivot in relation to a pivot axis extending in the longitudinal direction of the housing tube independently of each other in relation to the output drive slide, and the guide faces of the other, second guide face pair are engaged by second bearing elements arranged of the output drive slide, the transverse position of the second bearing elements assumed in the axial direction of the first transverse axis in relation to the output drive slide being able to be varied.
