Abstract: The guidance means (20) according to the invention is used for guiding the rolling or sliding movement of objects (10) along a predetermined or preset path or route, whose course is freely selectable within wide limits in space. The guidance means (20) has a guiding means extending without interruption over the predetermined path in the form of a cage-like arrangement of a plurality of at least limitedly bendable guide rails (21) and a plurality of support or carrying elements (22), which are arranged in mutually spaced manner along the predetermined path and which hold the guide rails (21) in parallel and in an at least partly spaced manner in the predetermined, cage-like arrangement. The guide rails (21) advantageously comprise a limited flexible, continuously manufacturable metal or plastic profile.

Abstract: A bearing device is used as a bearing for a pivot of a head stack assembly to thereby make a hard disc drive thin. Widths of first and second inner races 12a and 13a are set to be smaller than the widths of first and second outer races 12b and 13b. Even if first and second bearings 12 and 13 (outer races 12b and 13b) are mounted on a shaft 9 in contact with each other, a space S is formed between the first and second inner races 12a and 13a. From this structure, in the case where a pre-pressure is applied to the second inner race 13a, it is possible to adjust the pre-pressure in a wide range. In the prior art, it has been necessary to provide an annular projection or a spacer for keeping a space for application of the pre-pressure. However, the present invention makes possible to dispense with the annular projection or the spacer. Corresponding to this, the width of the bearing device 10 is shortened.

Abstract: A ball bearing assembly includes a polymer outer bearing ring molded over and partially enclosing a metal annular outer raceway. The metal annular outer raceway may be economically formed from sheet metal or wire. The polymer outer bearing ring may be mounted within a metal housing to provide support and/or self-alignment capability.

Abstract: A linear motion system (10) comprises circulating balls (38) which run along steel rods (36) and on a shaft (18) within a support (20) of novel design. The latter consists of a light metal base (22) holding pairs of steel rods (36) in longitudinal channels (34) which open out towards the shaft (18). The generally cuboid or -shaped base (22) includes a longitudinal cavity (28) that is laterally joined by at least two ball channels (30) which are placed under a radial angle (.alpha.) relative to each other. The axes of neighboring longitudinal channels (34) are pairwise in planes (N) perpendicular to radial directions (R) in which the balls (38) are tangent to the associated shaft (18). Near outer zones (26) of base (22), set screws (46) are arranged at longitudinal distances (s) for adjustment of the gap width (b) of a slot (40) that opens out towards the cavity (28). Base (22) has an opening (52) associated to each ball channel (30), to be closed by a plug (54), a screw cap, etc.

Abstract: A pressure sealing bearing (13) for use in a protective environmental suit (10) is provided. The bearing employs inner and outer races (44,54) composed of a light weight, relatively weak material, such as a plastic or aluminum alloy. To provide long wear and adequate strength, the bearing includes contoured race wires (46,48,56,58) and an interlock mechanism (72,74). The ends of inner race wire 48 are designed to butt against one another to control the deformation due to compression of the inner race (44) when pressure is applied to the bearing. The ends of outer race wire 56 include interlocking hooks (82,84) which control the deformation due to tension of the outer race (54). In this way, the bearings achieve the performance of all stainless steel bearings while providing weight reductions of at least 60%.

Abstract: Bearing rings are carried one each in a shaft end and in a cap and seat against a ball element therebetween. Preloading of each ball element at the shaft ends is achieved by rotation of the cap along a threaded end segment of a bushing of a bearing assembly. A set screw on the cap seats against a circular wall of the bearing assembly for infinite bearing adjustment. A sealed chamber for lubricant is defined by the cap and permits direct application of lubricant to the ball element at each end of the shaft.

Abstract: A bearing utilizing a plurality of wires has the races for the roller bodies provides individual lining strips between each wire and the groove walls of the receiving structural members of the bearing.

Abstract: The invention concerns an annular multi-row bearing with shaped-wire races with an inner and an outer race, each of which constitutes part of the tracks for the rolling components, and with rolling components accommodated between them. The particular object is, in addition to others, to create a bearing that, although stable, is resilient enough when transverse forces occur to allow both races to twist in relation to each other within certain limits, avoiding stress.The invention attains this in that the contact or rolling surfaces between the races and the rolling components are provided with a contour that deviates from the rectilinear and mutually surrounds itself and in that these contact surfaces are shaped and/or positioned such that there is a four-point bearing in each track.This principle can be embodied with either ball bearings or roller bearings, whereby only three shaped wires are preferably employed. The angles of support range, depending on the type of bearing, between approximately 30.degree.

Abstract: A bearing assembly of the type formed from two inner and two outer race members Siamese stamped from flat stock, so that there are annular gaps left between the two pairs of confronting race members. Seal supporting housing members secured to the inner races provide sealed lubricant reservoirs that feed to the ball complement through the annular gaps, and also prevent the outer race members from separating from the inner race members at the annular gaps.
