In a bearing and support for use either as a bearing, per se, or as a bearinged support for other items and incorporating the bearing of this invention; the bearing includes at least a pair of rotatable members that rotate or counter-rotate about a common axis, a shaft supporting the rotatable members for rotation about its common axis; roller, ball, sleeve, or other forms of bearings disposed between the rotatable members and the shaft to facilitate the rotation of the members therearound; a structural member incorporating a series of keepers upon its upper and lower edges and which retain races or tracks, and being disposed for having one of the rotatable members associated thereon to provide a bearing suspended support for holding other items, or the body of a person. The bearinged support may be of a circular or of a nonannular design, to carry both radial and thrust loads, thereby increasing its various uses, which include, among other concepts, the application of the support for use in conjunction with gymnastic equipment, such as to provide safety during usage of the horizontal bar, balance beam, the trampoline, or even during tumbling, and in addition, the support has usage for facilitating the plight of the invalid. Furthermore, the invention can be used as a bearing to support both radial and thrust loads, can be used in cams, machinery, dollies, manufacturing transfer machines, conveyors, and safety equipment, among other items. A crossarm for movement along a track provides the overhead structure for holding the bearinged support at a variable or fixed disposition therebelow, as during use of the support for one of the aforesaid purposes. The structural member and its races of the support are separable, being held together by means of an adjustable bridging member, thereby advancing the state of the art by allowing the opening up of the bearing races and wrapping the assembly around the shaft, body or load, and by use of the adjustable bridge draw the assembly and load into continuous contact through a tightening and locking the bridge.
