Abstract: An oil-lubricated anti-friction bearing is provided for a horizontal arrangement of a rotational axis with a shaft seal that separates a bearing inner chamber, which accommodates rolling bodies, from a bearing outer side, and has a clamping arrangement which acts on the shaft seal from a bearing outer side in order to fix the shaft seal axially. The clamping arrangement has an outlet for oil.

Abstract: The invention relates to a process for producing a rolling bearing cage, in particular for large rolling bearings, wherein a steel strip with openings for in each case one rolling body is provided and bent to form a ring, wherein, for thermal coating with a thermoplastic powder, the ring is then heated to a temperature above a minimum coating temperature, wherein the ring is then dipped into a fluidized bed comprising the thermoplastic powder, wherein, during the residence time of the ring in the fluidized bed, plastic powder adheres to the ring, melts and forms a continuous coating, and wherein the ring is removed from the fluidized bed after the coating. The invention also relates to an apparatus for carrying out the process.

Abstract: The invention relates to a method for producing a rolling bearing cage for a rolling bearing comprising at least one row of rolling elements. In the method according to the invention, a ring or a ring element made of a metallic solid material is provided and shaped by a forming process and/or a cutting, material-removing process into an annular or segmented main body of the rolling bearing cage. The main body has openings for receiving a respective rolling element, the main body being heated to a temperature above a minimum coating temperature for thermal coating with a thermoplastic material powder, wherein the main body is then immersed in a fluidized bed containing the thermoplastic material powder, wherein thermoplastic material powder adheres to the main body, melts and forms a contiguous coating while the main body is present in the fluidized bed, and wherein, after the coating, the main body is removed from the fluidized bed.

Abstract: A method is provided for supporting rotatable devices, particularly a medical scanner having an inner ring and an outer ring. According to the invention, the inner ring and outer ring are guided without contact in the axial and/or radial direction by the magnetic field of electromagnets, and the distance between them is monitored and controlled by means of distance sensors. For a bearing implementing said method according to the invention, the outer ring is made in multiple parts and has a U-shaped cross section that is open to the inside in the assembled state, into which the inner ring (1, 10, 11) extends, and electromagnets and distance sensors are disposed in the axially and radially opposite areas of the inner ring or outer ring.

Abstract: A method is provided for producing a bearing ring (1) for large-size rolling bearings including at least one track (3) that is provided with a hardened peripheral layer. With the method the peripheral layer that is to be hardened is exposed to the electric field of an inductor in order to be heated and is then quenched. At least two inductors (2) are disposed above a common zone (a) of the annular track (3) that is to be hardened at the beginning of the hardening process. These inductors (2) heat the opposite peripheral layer to a hardening temperature at this location. The inductors (2) are moved in the opposite direction along the annular track in order to heat the adjacent central zones (b). Sprinklers (5) that are directed onto the heated peripheral layers are turned on following a short distance, and the peripheral layers are quenched starting from the center of the zone (a) that was heated at the beginning.

Abstract: A bearing ring for a large roller bearing is formed with at least one annular race which is hardened by heating by juxtaposing that race with an inductor across a spacing which is maintained during the heating and then quenching. The spacing is controlled selectively so that it is: 1 to 2 times a depth T of hardening of the surface layer for a radial-bearing race, 0.6 to 1 times the depth T of hardening of the surface layer for an axial-bearing race whose inner diameter corresponds to an inner diameter of the bearing ring, at an outer edge of the axial-bearing race, 1.5 to 2 times the depth T of hardening of the surface layer for the axial-bearing race whose inner diameter corresponds to an inner diameter of the bearing ring at an inner edge thereof, and varying continuously between the outer edge and the inner edge, and uniformly 0.6 to 1 times the depth T of hardening of the surface layer for an axial-bearing race whose inner diameter is greater than that of the bearing ring.
