Abstract
The pretensioning element serves to elevationally position or pretension or bias a circulation track bearing member. In order to reduce the requirements imposed upon the support and mounting surfaces during manufacture, with regard to alterations in parallelism during pretension adjustment and during load changes, that is in the range of elastic deformation, there is provided a housing which comprises at least one guide track. Two wedge members are displaceably guided in the guide track by means of tightening screws or bolts. The wedge members contain first wedge surfaces. A support plate is provided and comprises two second wedge surfaces which cooperate with the first wedge surfaces of the wedge members.
