  • Patent number: 8500336
    Abstract: Guide roller rotating bearing for a metal melt bath includes pivot arms and a roller bearing device arranged on each of the pivot arms. The roller bearing device includes an outer ring, cylindrical rollers and an inner ring. The outer ring includes first and second outer ring flange members. The outer ring is fixed to a pivot arm. The cylindrical rollers are configured as rolling elements. The inner ring has first and second inner ring flange members. The first and second outer ring flange members and the first and second inner ring flange members are configured to fix the cylindrical rollers in an axial direction. A shaft end includes a protective covering disposed in the roller bearing device. The protective covering includes a protective covering material that exhibits a wear-resistance which is higher than a wear resistance of the shaft end.

  • Patent number: 7156920
    Abstract: The coating device (10) for coating a metal band or strip (12, 12?) in a melted metal mass (14 ) comprises a shaft (16, 18) rotatably supported in the melted metal mass (14) by a slide bearing (261, 262) is formed by a bearing housing (32) and an open bearing shell (34) held therein, with two bearing surfaces (36) . Between the two bearing surfaces (36), the bearing shell (34) comprises a deformation zone (40) with a deformation element (44) . With high radial forces of the shaft occurring, the two bearing shell halves (381, 382) are slightly spread. The flexible deformation zone ensures that the two bearing shell halves remain interconnected and resist breaking in this area.

  • Publication number: 20040177808
    Abstract: The coating device (10) for coating a metal band (12,12′) in a melted metal mass (14) comprises a shaft (16,18) rotatably supported in the melted metal mass (14) by a slide bearing (261, 262), for guiding the metal band (12). The slide bearing (261, 262) is formed by a bearing housing (32) and an open bearing shell (34) held therein, with two bearing surfaces (36). Between the two bearing surfaces (36), the bearing shell (34) comprises a deformation zone (40) with a deformation element (44). With high radial forces of the shaft occurring, the two bearing shell halves (381, 382) are slightly spread. The flexible deformation zone ensures that the two bearing shell halves remain interconnected and cannot break in this area.
