    Abstract: The present invention relates to spiral groove bearings. In order to provide a spiral groove bearing with enhanced efficiency, for example with reduced weight and increase of load bearing capacity at nominal operation frequency, a spiral groove bearing arrangement (10) for rotatably supporting a rotating arrangement is provided that comprises a first sub-bearing (12), at least a second sub-bearing (14), and a coupling device (16). The first sub-bearing is a main spiral groove bearing (18) configured to carry a load of the rotating arrangement at a nominal operation frequency range, and the second sub-bearing is an auxiliary bearing (24) configured to carry the load of the rotating arrangement from starting and landing to the nominal operation frequency range. The coupling device is configured to couple the first sub-bearing and the second sub-bearing in a frequency range from starting and landing to the operation frequency range. Further, the coupling device is also configured to de-couple the second sub-bearing at the nominal operation frequency.

    Abstract: A radial sliding-contact bearing for rotary rolls has a cylindric fixed inner portion (2), a sleeve (4) rotatable thereon, and a gap (6) between the sleeve and the inner portion intended for a water film which in operation forms a rotary bearing for the sleeve. On its peripheral surface the inner portion has recesses (8') for facilitating an even distribution of the water over the surface of the inner portion (2) in operation. The water is fed to the gap (6) through first and second longitudinal rows of nozzle openings (14, 16) in the peripheral surface of the inner portion (2), which are connected to a common water supply channel (18) in the inner of the inner portion. As seen in the rotational direction of the sleeve, the nozzle openings, more particularly, end in the periphery of the inner portion before and behind, respectively, a longitudinal surface groove (8') in the upper side of the inner portion, said surface groove (8') serving for conveying on water coming from the first row of openings (14) and forming part of said recesses. The openings (16) in the second row, which is located before the area of the horizontal radial plane of the sleeve, have a water outlet direction (26) with a not unessential resultant in said rotational direction (24).
