A roller arrangement with at least two rollers arranged axially parallel, wherein a respective nip is formed between adjacent rollers, each of the rollers having a roller journal at both of its two axial ends, each roller being pivot-mounted via its two roller journals, at least two bearings being arranged axially adjacent to one another at least on both of a first roller journal of a first of the rollers and an adjacent first roller journal of a second of the rollers, wherein a compressive stress is generated between an inner bearing on the first roller journal of the first roller and an outer bearing on the first roller journal of the second roller and a tensile stress is generated between an outer bearing on the first roller journal of the first roller and an inner bearing on the first roller journal of the second roller or vice versa.

A roller for a metallurgical plant is provided. The roller is modified in such a way that the camber thereof can be set in a simple and robust manner. The roller axle is connected to the roller shell at one point, preferably at at least two points, via a ring, and the ring has a heating element, wherein the height H of the ring can be changed by ΔH as a result of the heating of the heating element.

A roll stand (1) includes a roll (3), in particular a backup roll, mounted via oil film bearings (2). Each oil film bearing (2) has a sealing system for sealing the oil film bearing (2) to prevent oil leakage and a coolant ingress. The oil film bearing (2) is integrated into an oil-circulating lubrication system (4), which is fluidically connected to the oil film bearing (2) via oil feed lines (5) and an oil discharge line (6). A first sensor (11) is arranged in the oil feed line (5) and a second sensor (12) is arranged in the oil discharge line (6). The two sensors (11, 12) are designed to determine the coolant content in the relevant oil volume flow.

A method and an equipment permitting to optimally handle and support a roll made of at least an inert material and transfer the torque from a bearing to a roll or the other way around without damaging them, the roll and bearing being immersed in molten metal.

A bearing box for a rotating roller for supporting or transporting a high-temperature object. The bearing box includes a bearing and seal units disposed therein. A cooling jacket is disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit. The cooling jacket has a cooling water inlet and a cooling water outlet, and the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet.

A pass roll for a hot-dip galvanized steel sheet manufacturing facility, the pass roll includes: a roll body; and a heat-resistant felt layer covering the roll body, wherein the heat-resistant felt layer has a thermal decomposition temperature of 420° C. or higher and has a surface hardness evaluation index at 400° C. of more than 0.11 μm/N.

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 roller bearing seal includes an insert part and a polymer part connected to the insert part, and the insert part includes an annular-disc-shaped middle section having a radially inner deflection and a radially outer deflection, and a first ratio (L2/L1) of an axial length (L2) of the outer deflection to an axial length (L1) of the inner deflection is less than 0.65.

A rolling-element bearing assembly includes first and second bearing rings that form a bearing interior between them and a plurality of rolling elements disposed in the bearing interior and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier and a seal element having at least one primary seal lip for sealing the bearing interior and a secondary seal lip for sealing against external contamination. The seal element is connected to the seal carrier such that the primary seal lip and the secondary seal lip abut axially against an axial end surface of the second bearing ring.

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.
