An endless linear motion roller bearing assembly includes a rail, a slider and a plurality of rollers interposed between the rail and the slider. The slider is provided with at least one endless circulation path which includes a load path section defined between the slider and the rail, a return path section and a pair of curved connecting path sections, each connecting the corresponding ends of the load and return path sections. The rollers roll along the endless circulation path back and forth...

A rectilinear slide ball bearing consists of a slide board, a pair of cover members, a rail-like track mount and a multiplicity of balls. The slide board assumes a substantially gate-like configuration and has a pair of load ball grooves formed in the inner surface of a recession in the longitudinal direction. The cover members include ball circulation passages for constituting ball endless tracks. The balls roll between the load ball grooves of the slide board and ball rolling grooves formed in...

The bearing may be used in the housing of a constant velocity universal joint such as a front-wheel universal joint drive for motor vehicles. The bearing has a generally rectangular roller block provided with raceways around its entire periphery. Rollers fill all of the raceways. The ends of the raceways are defined by a pair of flexible end plates. The end plates yieldingly guide the roller ends.

Apparatus is disclosed for the strain-free mounting of a component, such as a mirror 11, to a base in a manner that allows for differential thermal expansion or contraction to take place between the component and the base without distortion of the component. The mounting apparatus of the invention makes use of a linear bearing 10 that is rigid in all directions except one. Such a linear bearing is used at two or more points of support on the circumference of a mounting circle A. Relative motion ...

A hydrostatic bearing system utilizing ferromagnetic fluid exclusively as working fluid including that used for sealing for preventing the ferromagnetic fluid itself from escaping outside the bearing. In order to accomplish the objects and function, the hydrostatic bearing system proposed here comprises, in addition to ordinary parts or components used in the conventional type, a fluid chamber for containing the ferromagnetic fluid as a working fluid, a circulating passage, at least a recovery g...

In a business forms press and method wherein a wide, continuous web of paper is separated into a plurality of business forms width sections, a web separating unit provides pairs of bars for each web section, arranging the pairs of bars so that the axis of these bars is at an obtuse angle to the longitudinal direction of the press and at an obtuse angle to the path of the webs, arranging the pairs of bars so that their distance between the axis thereof and the angle of the plane through the axis ...

A shaft support comprising a shaft supported by a radial and an axial static fluid bearing, which shaft is rotatably arranged in a bearing sleeve and is provided with a flange-shaped compensation member, of which a part is situated in a compensation space. The compensation space is connected to a pressure source so that a radially acting resulting force is exerted on the compensation member and the shaft. The shaft support is particularly suitable for use with comparatively accurate bearings hav...

A pinion shaft of an axle drive bevel pinion mating with a bevel gear is disposed in two tapered roller bearings, the joint outer race of which is flanged onto the axle housing. In order to lubricate the tapered roller bearings with splash oil and avoid dirt deposits in the bearing area, the outer race of the tapered roller bearings has an oil feeding duct to a collecting pipe arranged above, and at its underside, an oil return duct to the transmission oil sump.

A bearing structure in particular for use in a meter having an axis of a pointer comprises a bearing support member having an internal thread and bearing member for supporting the axis rotationally, and the bearing member adapted to be fixed to the bearing support member, and the bearing member being formed of a synthetic resin and having an outer periphery. On the outer periphery of the bearing member, there are formed at least one complete thread portion having an external thread formed on the...

The present invention relates to a guidance system on a machine, especially a machine tool, consisting of a twist-resistant, vibratioin damping support body, of concrete for example, and at least one body fastened thereon or integrated therein, which is not of itself twist-resistant, and which forms the guidance ways. In order to endow such guidance ways with minimal thermal expansion and elasticity, make them very hard, give them good low-lubrication running characteristics, and enable them to ...
