Abstract
The locking cylinder unit (20) has a spindle (35) which is axially movable relative to the cylinder (21) and fixed to a support body other than the second axial bearing, which takes the axial forces acting on the spindle. The second axial bearing has a rolling bearing movable in the direction of the longitudinal axis (29) of the cylinder, which is sprung by a spring acting in the first direction (28).
