A method for surface treatment of a workpiece includes providing the workpiece with hardened workpiece surface, clamping the workpiece, removing material from the hardened workpiece surface with a material removal tool to produce a machined surface with first machining tracks, and rolling the machined surface with a rolling tool by overlapping the first machining tracks to produce a rolled surface with second machining tracks. A distance between the material removal tool and the rolling tool measured in an axial direction of the workpiece is varied in an oscillating manner. The material removal tool may be advanced in the axial direction at a constant speed and the rolling tool may be advanced in the axial direction at an oscillating speed, or the rolling tool may be advanced in the axial direction at a constant speed and the material removal tool may be advanced in the axial direction at an oscillating speed.

A motor assembly includes a shaft, a bearing, at least one fluid channel, a temperature sensor, a lubricant supply pump, and a controller. The bearing defines a bearing interface against which the shaft rotates. The at least one fluid channel is fluidly coupled with the bearing interface. The temperature sensor detects a temperature of the bearing. The lubricant supply pump is fluidly coupled with the at least one fluid channel to transport lubricant from a lubricant supply to the bearing interface via the at least one fluid channel. The controller receives the bearing temperature from the temperature sensor, determines a difference between the bearing temperature and a supply temperature of the lubricant, determines a lubricant flow rate based on the difference, and transmits a control signal to the lubricant supply pump to cause the lubricant supply pump to transport the lubricant to the bearing interface at the lubricant flow rate.

A bearing block unit for supporting a continuous casting roll, including a bearing block and a roller bearing disposed inside the bearing block. The bearing provides an inner ring raceway, an outer ring raceway, and at least one row of rolling bodies disposed between the inner and outer ring raceways. The inner ring raceway is formed by a complete and continuous independent inner ring. The inner ring is fitted on a roll shaft of the continuous casting roll during installation, for the purpose of supporting the continuous casting roll. The outer ring raceway is at least partially formed by processing of an inner surface of an inner hole of the bearing block. The present invention also relates to a continuous casting roll line and a continuous casting machine using the bearing block unit.

A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

The invention relates to a seal device (1) for sealing two bearing elements which rotate relative to each other about an axis (D), in particular for sealing a rolling bearing. The seal device (1) includes a sealing section (2) for sealing purposes and a fastening section (3) for holding the seal device (1) against a bearing element (21). The sealing section (2) is arranged at one end of the fastening section (3) and includes a free end (E) opposite thereof. All the sections (2, 3) have a common carrier element (4) and at least one sealing element (5), and all the sections (2, 3) extend in the radial direction (R) and/or in the axial direction (A). The fastening section (3) extends at least partly in the axial direction (A) such that the carrier element (4) and the sealing element (5) rest directly against a bearing element (21) in order to form a clamping seat in the radial direction (R) by the carrier element (4) in order to hold against a bearing element (21) and a static seal by the seal element (5) in order to seal against a bearing element (21). The invention further relates to a seal assembly (20) for a rolling bearing, in particular for a wheel bearing assembly, including a bearing element (21) and a seal device (1).

A rolling contact bearing, wherein the surface of the raceways of an outer member and/or an inner member are randomly formed with an innumerable number of microconcavelike pits, the surfaces are provided with said pits having a surface roughness value smaller than 0.25 microns and a skewness Rsk value such that −3.5<Rsk<−1.0.

A rolling bearing device includes a rolling bearing that includes an outer ring having an inner peripheral surface on which a first raceway surface is provided, an inner ring having an outer peripheral surface on which a second raceway surface is provided, and rolling elements interposed between the first and the second raceway surfaces; a strain sensor configured to detect a strain of the rolling bearing; and a fixation portion configured to fix the strain sensor to a peripheral surface that includes at least one of an outer peripheral surface of the outer ring and an inner peripheral surface of the inner ring. The fixation portion fixes at least two locations in the strain sensor to the peripheral surface such that a detection region of the strain sensor and the peripheral surface are not fixed to each other, the at least two locations facing each other across the detection region.

A gas turbine engine component includes a ring comprising a single-piece component having an outer peripheral surface and an inner peripheral surface that surrounds an engine center axis, a plurality of outer diameter pedestals formed in the outer peripheral surface and circumferentially spaced apart from each other, and a plurality of inner diameter pedestals formed in the inner peripheral surface and circumferentially spaced apart from each other. A plurality of recesses are formed in the outer peripheral surface and are circumferentially spaced apart from each other.

Aspects of the disclosure relate to processing sliding mechanisms. For instance, an assembly including a first component having a first sliding mechanism may be heated to a first minimum temperature for a first minimum period of time. Thereafter, a second component is pressed onto the assembly a first time such that the second component contacts the first sliding mechanism. Thereafter, the second component and the assembly may be subjected to a below-freezing temperature for a second minimum period of time. Thereafter, the second component may be separated from the assembly. The first sliding mechanism may be rotated relative to the first component. Thereafter, the second component may be pressed onto the assembly a second time such that the second component contacts the first sliding mechanism. Thereafter, the first component and the assembly may be heated to a second minimum temperature for a third minimum period of time.
