ABSTRACT:
Disclosed is a device for influencing in a controlled manner the load-bearing force of supporting rollers (SW) that rest on working rollers. The neck (WZ) of said supporting rollers (SW) which is provided with an extension (ZA) is mounted in roller bearings or sliding bearings that are disposed in a bearing-supporting housing of the rollers of a roller stand. The neck extension (ZA) is mounted in a supporting bearing. The outside of the housing (LG) of said supporting bearing is connected to the bearing-supporting housing. An intermediate housing (ZG) which is inserted in the housing (LG) of the supporting bearing cylindrically encloses the supporting bearing, is impinged upon by a piston cylinder unit (RB, SK), and can be displaced within said housing (LG) in a radial direction relative to the axis of the neck extension (ZA).
