to a certain extend. Vibration, an increase in the spindlepitch or the
use of rolling screw elements release the self-locking. Inthis case,
e.g., a brake motor should be included in the system. Forlower stroke

avaliable withan optional spindle end safety feature. This means the
threaded spindleis locked before the safety sleeve is mounted, to limit
the stroke inextended position so that the spindle cannot be screwed out
of the gearunit. Attention: this safety feature means the safety sleeve
is by about20 mm longer.
