Definitions

  • the invention relates to a rolling stand according to the preamble of claim 1.

  • the structure of the rolling stand depends on the number of rollers, the position of the rollers, the shape of the rollers, the forces acting during rolling and the accuracy requirements of the rolling stock. There are both rolling mills with only one as well as those with several nach- or side by side arranged roll stand (s).
  • a “floating” bearing (also often referred to as a “flying” bearing) is understood to mean a bearing of an element extending around an axially extending axis of rotation, such as the roller, which bearing (with respect to the axially extending rotational axis of the rotating element) in the axial direction has a game / allows. That is, the (floating) element is in the axial direction not clearly fixed.
