A bearing system including a wheel assembly transmitting load to a damping assembly, wherein the wheel assembly is configured to rotate angularly relative to the damping assembly.

A fluid bearing includes a housing including an internal plenum disposed in the housing and an inlet in fluid communication with the plenum, wherein the inlet is configured to provide fluid to the plenum from an external source, a cushion surface facing away from the housing and the plenum, one or more nozzles positioned between the cushion surface and the housing, wherein the one or more nozzles extend from the plenum to the surrounding environment, wherein the one or more nozzles are configured to produce an annular curtain of fluid flowing at a velocity of at least Mach 1 and disposed about the cushion surface in response to a fluid flow entering the plenum from the inlet.

A rolling bearing, in particular a center-free large rolling bearing, having two concentric ball races with one ball race comprising a groove open toward the other ball race, and the other ball race comprising a scraper ring engaging into the groove, wherein the scraper ring is supported at the groove in the axial direction of the rolling bearing by at least two axial bearings arranged at oppositely disposed scraper ring front side and wherein the scraper ring is supported in the radial direction by at least one radial bearing which is arranged on the scraper ring jacket surface. The scraper ring is supported in the axial direction at the groove by a third axial bearing, wherein two axial bearings are arranged at the same side of the scraper ring at separate raceways offset from tone another in the axial direction of the rolling bearing.

The present invention relates to a system used in the offshore renewables or oil and gas industries for providing articulation at the end of a mooring line or a riser. The design uses a nested rubber segment (14) and orthogonal cylindrical bearings (12) to provide articulation with low resistance at both small and large oscillation angles. A relative rotational force applied between the axially loaded member (1) and the anchor assembly (4) causes the angle of the axially loaded member (1) to change to reduce such forces. The securement assembly comprises a bearing assembly (10) arranged to provide rotation about a pin (11). The bearing assembly (10) is arranged to provide two distinct stages for relative rotation. In the first stage, small relative rotations are accommodated by the flexion or deformation in the rubber layer (14). This deformation of the rubber layer (14) enables the axially loaded member (1) to rotate around the pin (11) and move relative to the anchor assembly (4). In the second stage, the further and subsequent movement of the axially loaded member (1) causes an articulating surface to physically slide over the bearing surface.

A roller circle assembly for heavy machinery includes an upper circular rail and a lower circular rail concentrically arranged about a central axis, and tapered rollers between the upper and lower rail. Each tapered roller includes a flange having an angled and convex flange contact surface that contacts the lower rail. The lower rail and/or the upper rail can include an angled surface configured for contact with the flange contact surface. The geometry of the rollers and the lower rail are configured to reduce the stresses applied to the rollers and lower rail due to contact between the flange contact surface and the angled surface.

A system and method that includes a device that is used in a particular method to install bearings into a lift cylinder yoke bore. The device includes use of a hollow bore hydraulic push cylinder that maneuvers a push plate along a threaded rod. The push plate sinks or sets into the bearing and applies pressure through the movement of the hydraulic push cylinder to place the bearing into a fit position without the abrasion that is usually associated with the installation of bearings into the lift cylinder yoke bore. The threaded rod attaches to a threaded bushing that is inserted into the bore and secured with the use of a pin. The threaded rod extends out of the bore opening and allows for the attachment of a bearing, push plate, hydraulic push cylinder, washer and nut.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

A sleeve bearing comprising a tubular body having an inner surface annularly about a longitudinal axis and an outer surface radially outward from the inner surface. The sleeve bearing includes a first side surface between the inner surface and the outer surface, and a second side surface between the inner surface and the outer surface. The sleeve bearing includes a first inner edge between the first side surface and the inner surface, and a second inner edge between the second side surface and the inner surface. The sleeve bearing includes lubricant reservoirs in the inner surface elongated along an elongation axis. An angle between the elongation axis and the inner edge is between 0 and 90 degrees. The lubricant reservoirs are in an interrupted pattern annularly around the inner surface so a portion of the inner surface between the first inner edge and the second inner edge is uninterrupted.

A pin retention system includes a pin having a circumferential groove disposed along the pin, and a plurality of retention elements sized to sit within the circumferential groove, each of the retention elements including a plurality of holes. The system also includes a plurality of dowels sized to slide within the holes in the retention elements.

The present application relates to a field of bearing technology and relates to a recirculating roller bearing, including a front cover plate, a rear cover plate, an inner supporter, a sealing covering and a plurality of rolling carriers and at least one connector, in which the front cover plate and the rear cover plate are detachable connected on two sides of the inner supporter respectively; a circulating guiding path is defined by the front cover plate, the rear cover plate, the inner supporter and the sealing covering, the circulating guiding path includes a sealing portion and an opened load-bearing portion; the rolling carriers are filled in the circulating guiding path, each of the rolling carriers forms a rolling fit with the inner supporter, and each of the rolling carrier forms a rolling fit with a retractable fork when passing the opened load-bearing portion of the circulating guiding path.
