The present invention provides a magnetic-hydraulic double-suspension bearing experiment table. In the experiment table, four blind holes are uniformly processed on left and right side surfaces of the two radial stators for magnetic-hydraulic double-suspension bearing; four countersunk through holes are uniformly processed on left side surfaces of the left supporting part of the fixed bracket and the right supporting part of the fixed bracket, and the radial stators for magnetic-hydraulic double-suspension bearing are fixedly connected to the upper end of the left supporting part of the fixed bracket by countersunk screws. In addition, the two radial stators for magnetic-hydraulic double-suspension bearing are processed with stops to ensure that the two radial stators for magnetic-hydraulic double-suspension bearing are concentric with the left supporting part of the fixed bracket and the right supporting part of the fixed bracket.

A support structure includes: a support frame as a shaft support member for supporting two shafts; a bush provided on each of the two shafts in a slidable manner; a cover support member connected to the multiple bushes and configured to support the cover; a first connection member for connecting one end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame will not change; and a second connection member for connecting the other end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame can change.

A support structure includes: at least two shafts extending in a first direction in which the cover expands and contracts, and arranged inside the cover so as to be spaced from each other in a second direction that intersects the first direction; a bush provided on each of the at least two shafts so as to be slidable along the shafts; and a cover support member. The cover support member includes a main part supporting the cover, a first connection part connecting the main part and the bush so as not to change the relative position between the bush and the main part, and a second connection part connecting the main part and the bush in a manner that the relative position between the bush and the main part can be changed.

An air rest button system comprising a body element and a plunger element configured to accept a rest button. The plunger element generally is configured to be inserted into a base in the top of the body element. The plunger element in turn has a bore or hole therein configured to receiving an air rest button, which may be substituted for other air rest buttons, facilitating the modularity of the present system.

In a moving body guiding device which supplies lubricating oil between a guiding surface of a supporting body and a sliding surface of the moving body and guides a moving body, a lubricating oil pocket having a periphery enclosed by a land portion is provided on the sliding surface of the moving body, a closed loop oil groove is formed along the inside of the land portion, a front portion and a rear portion inside the lubricating oil pocket communicate with one another by means of a lubricating oil pocket return passage at least partially opening in the oil groove, and lubricating oil that has accumulated in the rear portion, in a movement direction, concomitant with movement of the moving body, flows to the front portion in the movement direction.

The invention relates to an adjusting device for spatially adjusting the position of an object, comprising a plurality of plate elements which are arranged one over the other and which have radial guide structures that engage into one another at mutually facing sides, wherein at least one pair of movement plates and a pair of inclination plates are arranged on a base. The movement plates have a constant thickness, and the respective upper radial guide structures and lower radial guide structures of each movement plate are offset eccentrically relative to one another. The inclination plates have a variable thickness, and the respective upper radial guide structures and lower radial guide structures of each inclination plate are arranged concentrically to one another.
