A bearing closure device has a externally threaded ring that can be slid onto a roll journal. One stop close to the roll barrel and one stop away from the roll barrel are provided on the roll journal in order to limit the axial movement of the threaded ring. A ring nut with an internal thread is screwed onto the external thread of the threaded ring. To facilitate safe screwing on and unscrewing of the ring nut and to keep screws pressure-free during the operation of the bearing a pressure ring is mounted between the bearing and the threaded ring in an axially displaceable manner. In addition, a plurality of screws can be screwed into axial threaded bores in the threaded ring in order to press against the pressure ring in the axial direction. Finally, the ring nut can be screwed or adjusted against the pressure ring.

A steel processing line includes a dip tub and a stab roll. The dip tub is filled with a quantity of molten metal. At least a portion of the stab roll is submerged in the quantity of molten metal. The stab roll includes two journals. Each journal is received by an opening defined by a roller sleeve including a ceramic or refractory material. The roller sleeve is disposed between each journal and a bearing block. An inner dimension of each roller sleeve and an outer dimension of each respective journal defines a clearance. The inner dimension of each roller sleeve and the outer dimension of each respective journal is configured such that the clearance persists as the stab roll and the pair of roller sleeves are heated by the molten metal. Alternatively, inserts are fastened to an outer surface of each journal in lieu of the roller sleeves.

The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) which has two roller pins (23, 39) and is mounted to supporting arms (1, 2, 34, 37, 54, 57) by means of ceramic journal bearings (20, 31), wherein the journal bearings (20, 31) are in each case arranged in a bearing receptacle (45, 55) of the associated supporting arm (1, 2, 34, 37, 54, 57). The invention is characterized in that at least one of the journal bearings (20, 31) in its associated supporting arm (1, 2, 34, 37, 54, 57) is fixed in the bearing receptacle (45, 55) by means of a force-fit that engages on the outer edge of the journal bearing (20, 31) and balances the different heat expansion coefficients of the journal bearings (20, 31) and the bearing receptacle (45, 55).

A hub unit includes: a bearing section including an outer ring, an inner ring disposed coaxially with and inside the outer ring, rolling elements disposed in a bearing inner space, and a sealing member sealing the bearing inner space at an end on a vehicle inner side; a hub ring including a body portion, and a wheel mounting flange portion on which a wheel is to be mounted; and a covering member protecting the bearing section from a foreign substance. The covering member is fixed to rotate integrally with the hub ring and the inner ring, and covers an end on the vehicle inner side of the bearing section. A part of the covering member opposing to an end surface on the vehicle inner side of the outer ring is not parallel to the end surface.

A bearing for holding a rotary conversion tool (10, 11) that includes two end rolling bearing devices (26, 28), at least one intermediate rolling bearing device (27) interposed between the end rolling bearing devices (26, 28), the end and intermediate rolling bearing devices (26, 27, 28) being intended to engage with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo′) at the intermediate rolling bearing device (27).

The invention relates to a bearing arrangement (12) for a part to be mounted such that the part rotates about an axis, such as a cylinder, roller, drum or shaft, comprising at least one rolling bearing (23), which is accommodated in a bearing housing (27), which is mounted movably in an arrangement housing (29) in a linearly movable manner by at least one linear guide (28), and also including an actuation device (1) for effecting a linear shifting movement of the bearing housing perpendicularly to the axis between a rest position and a working position. The actuation device includes at least one prestressed spring element, which presses the bearing housing into the working position, and at least one hydraulic or pneumatic device for generating a restoring force acting counter to the spring element for moving the bearing housing into the rest position.

A support bearing, for example for straighteners, having an outer ring, an inner ring and rolling bodies that roll between the outer and inner ring on raceways. A bending moment prevails between the rings as a result of a load with a fixed direction of action. To compensate for the bending moment, an outer raceway of the inner ring and/or an inner raceway of the outer ring includes a profiling with a variable diameter in the axial direction. The profiling is adapted or approximated to a non-cylindrical bending line caused by the bending moment in the rolling contact, and the bending line is defined by a line, on which bending forces which are transmitted from the inner ring to the rolling bodies and are caused by the bending moment lie substantially perpendicularly. As a result, the disadvantageous edge loading in a given load direction is suppressed, with the result that more rolling bodies can transmit load between the rings at the same time.
