A thrust bearing assembly in which each thrust pad is individually mounted on a deflection element. An embodiment of the invention comprises a rotating bearing runner having a wear resistant face and a stationary bearing carrier defining a plurality of cavities disposed annularly around the carrier. A deflection element, such as a Belleville washer, is disposed in a cavity of the plurality of cavities and a pad is disposed over the deflection element. The pad is at least partially disposed within the cavity. The wear resistant face of the rotating bearing runner contacts the pad.

An improved compression load ball joint assembly consisting of a metal housing having an open end and an internal cylindrical chamber which at least partially encloses a portion of a movable stud member, a lower metal bearing, an upper metal split bearing, and a Belleville washer. The upper metal split bearing is disposed opposite the lower metal bearing to engage the movable stud member and the housing simultaneously. The upper metal split bearing is configured to slide within the housing to provide for a constant wear surface against the movable stud member. The lower metal bearing, upper metal split bearing, Belleville washer, and movable stud member are contained within the housing by a cover plate concentrically disposed about the movable stud member and secured within the open end of the housing.

An intervertebral spacer device includes first and second plates disposed in a spaced apart relationship, each plate having an inner surface and an outer surface, the inner surfaces of the opposing plates facing one another. The device also includes at least one restoring force providing element disposed between the inner surfaces of the plates, wherein a compressive load applied to the outer surfaces of the first and second plates is counteracted by the at least one restoring force providing element. The at least one restoring force providing element includes at least one slotted belleville washer having a convex shape when unloaded and a flatter shape when loaded, whereby one or more slots of the belleville washer widen when compressively loaded, and whereby the at least one slotted belleville washer is unloaded when no load is applied to the outer surfaces of the first and second plates, and is loaded when the compressive load is applied to the outer surfaces of the first and second plates. The second plate has an annular groove formed in the inner surface of the second plate, the device including a retaining wall and a retaining ring, whereby a wide end of the at least one belleville washer is captured by the retaining wall and the retaining ring for maintaining the wide end adjacent the inner surface of the second plate.

A strike plate mounting bolt assembly for resiliently mounting a strike plate to a door. The strike plate mounting bolt assembly includes a bolt and a post wherein the bolt is securably engageable with the post. The bolt is inserted through a bore in the door and the post is inserted through a bore in the strike plate. A resilient member such as at least one Belleville washer is disposed between a head of the post and a cavity in the strike plate wherein the at least one Belleville washer is compressed between the post head and cavity upon securing the bolt and post together to provide a resilient mount between the door and strike plate. The at least one Belleville washer may be a number of Belleville washers selectable stacked to form a pack of Belleville washers. By varying the number and orientation of the Belleville washers, the force / deflection characteristics of the pack may be tuned to accommodate the needs of a variety of electromagnetic lock design features.
