A bearing body is provided. The bearing body includes first and second support surfaces inclined so as to slope upward from a side on the imaginary central vertical plane passing through an axis of a rotating shaft to be supported toward one and the other outer sides in the width direction of the rotating shaft. First and second transitional regions that respectively make transitions from the first and second support surfaces to a first and end surface of the bearing body on one side in the axial direction of the rotating shaft have a curved shape projecting obliquely upward such that an orientation of a normal line changes from a perpendicular direction to a parallel direction with respect to the axis of the rotating shaft toward one side from the other side in the axial direction of the rotating shaft.

A sliding bearing element with a first layer having a radially inner surface includes a measuring device arranged on the radially inner surface of the first layer. The measuring device includes, in the order indicated, a first electrical insulating layer, a sensor layer and a second electrical insulating layer. A sliding layer is arranged on the second electrical insulating layer.

The disclosure concerns a sliding component and a method of manufacturing a sliding component. The sliding component includes a substrate and an electrical component. The substrate has a front surface and a rear surface and comprising an electrically-insulating substrate portion extending through a metallic substrate portion, and an electrical connector extending through the electrically-insulating portion between the front surface and the rear surface. The electrical component is arranged at the front surface of the substrate and electrically connected to the electrical connector.

A bearing adapter for a disk-shaped accessory tool which has two sides. The bearing adapter includes a bearing unit configured to reduce a bearing recess of the accessory tool. The bearing unit is configured to adjoin the accessory tool and to enclose a portion of the accessory tool on the two sides when the bearing unit is mounted on the accessory tool.

The present invention highlights a lemon shaped guide that may be used in a rotating machine to suppress excessive rubbing. Rubbing, between a rotor and a guide, is critical in industries; since, it may even lead to severe damages. The lemon shaped guide is based solely on the mechanical design, that is more economical and quickly implementable than the other traditional techniques, such as circular guide, or more advanced sophisticated devices, for example, magnetic bearings. The lemon shaped guide is designed from two circles—having the same radius, and centers on the same line with some distances—which are the most significant designing parameters. Once equipped with a rotating machine, the lemon shaped guide may perform better at minimizing rubbing, between rotor and stator operating at higher speed, than the traditional circular shaped guide.

A sliding element for an engine may include a polymer-based overlay layer and a metallic substrate. The polymer-based overlay layer may include a polymer-based matrix, a metal particulate, and a pigment. The pigment may have a hardness of at least 4 on the Mohs hardness scale.

Provided is a half bearing constituting a sliding bearing that is unlikely to cause damage during an operation of an internal combustion engine. The half bearing includes at least one protrusion, and the protrusion projects outward in a radial direction from an outer circumferential surface. A recessed portion that is recessed inward in the radial direction from the outer circumferential surface is formed over the entire inner-circumferential length between the protrusion and a circumferential-direction end surface of the half bearing. Two radial-direction grooves are formed in the circumferential-direction end surface of the half bearing relative to the protrusion, and each of the radial-direction grooves is adjacent to each of recessed portion side surfaces. The radial-direction grooves extend in the radial direction along the recessed portion side surfaces and are separated from the recessed portion at a midpoint of the extension. An inner circumferential surface-side end portion in an extending direction of the radial-direction grooves is located between a recessed portion bottom surface and an inner circumferential surface of the half bearing. A groove width and a groove depth of the radial-direction grooves decrease from the position separated from the recessed portion toward the inner circumferential surface-side end portion and reach zero at the inner circumferential surface-side end portion.

A sliding member includes an overlay layer made of a resin on a side of a sliding surface of a bearing alloy layer. When a valley void volume Vvv (μm.sup.3/μm.sup.2) in the sliding surface of the overlay layer is defined as Vv1, Vv1 is in a range of 0.015≤Vv1≤0.200.

A half thrust bearing includes a slide surface which includes: at least two oil grooves extending in a radial direction; a plurality of pad surfaces located on both sides of each oil groove in a circumferential direction; and at least two first inclined surfaces each formed between the oil groove and the pad surface on a front side of the oil groove in a rotation direction of a crankshaft. A plurality of circumferential grooves are formed in succession in the radial direction on the first inclined surface. A plurality of oil drain grooves extends side by side to intersect the circumferential direction and the radial direction on the pad surface. A plurality of flat portions are formed each between the adjacent oil drain grooves. Each oil drain groove is open at a radially outer end and/or a radially inner end of the pad surface.

A bearing configured to actively damp vibration of a shaft in a turbine. In one implementation, the bearing can include actuating members that move in a manner that changes properties of fluid, typically a thin film of lubricant, disposed in the bearing to facilitate rotation of the shaft. These changes effectively manipulate the stiffness and damping of the thin film according to a time periodicity that matches a parametric anti-resonance of the bearing. In turn, the resulting interaction of vibrating modes is favorable to damp vibration amplitudes at critical speeds.
