to improve the corrosion protection at the connection site of the sealing cuff and the ball pivot , a ball joint with a sealing cuff , made of an elastically deformable material , is proposed , which is connected , with an edge profile , to a ball pivot in a positive - locking manner in the direction of rotation around the longitudinal axis of the ball pivot and has an elasticity that compensates for the maximum rotary and swiveling movements of the ball pivot relative to the housing .
