Safety nut SEM

The safety nut consists of a ballscrew unit and a safety unit. The safety nut basically works just like a normal ballscrew nut. If the axial play increases due to wear, ball breakage or ball loss, the thread of the safety unit comes into contact with the ballscrew. This means the nut cannot be penetrated. The normal function of the unit is guaranteed up to an axial play of 0.4 mm.
