The special characteristic is, that some very rigid maintenance-free bearing as connection to the bogie and a high elastic bearing as connction for the cradle carrier serves.Both bearings must implement large angle of rotation and torsion movements. The solution consists of the fact that in a formed steering bar a maintenance-free spherical bearing protected by means of seals, for a rigid connection and an elastomer bush with integrated likewise maintenace-free by means of seals cannons of spherical bush forthe flexible connection one integrated Each of the rotary stands is equipped with two indentically constructed GMT-Rod s
