Abstract: A ball screw drive having a threaded spindle and a spindle nut which coaxially encloses it at least partially. The spindle nut receives a ball deflector and therefore has an imbalance caused thereby. A force transmission element is positively connected to the spindle nut. The outer surface of the spindle nut has a recess which is dimensioned and arranged to serve as a stop or groove for the force transmission element and also contributes to the imbalance compensation of the spindle nut. An imbalance compensation method is also provided by fixing the action surface as a surface recess such that the smallest width of the recess is at least 3 times as large as the maximum radial indentation thereof. The filling up of at least parts of the recess by the force transmission element is accounted for and the recess is lengthened along the spindle nut for imbalance reduction.
