Abstract: A method and apparatus for mounting a rotating part between two bearings designed to transmit radial and axial forces without axial and radial play. Each bearing includes a rolling element positioned between an outer part and an inner race surrounding the shaft end. Each bearing also includes a conical sleeve in contact with an inclined surface of the inner race. A nut is threaded to the outer end of the conical sleeve such that rotation of the nut causes the centering of the shaft end within the bearing. The outer part includes a chamfer surface into which extends a shim. A screw is rotted to cause the shim to compress the outer part downwardly toward the inner race. The method for mounting the rotating part also includes the use of a stepped shoulder at one end of the housing to prevent axial movement of one of the bearing members. The opposite end of the housing does not include a stepped shoulder so as to allow easy insertion of the second bearing member.

Abstract: An orientation bearing ring for resisting radial loads, axial loads, and inclined moments. The ring includes first and second races each of unitary construction, opposed thrust faces of the races have roller thrust bearings between them with the axes of the bearings perpendicular to the axis of the ring. An additional row of bearings is disposed in opposed bearing tracks in the respective races, these bearings engaging their tracks at an oblique angle to the axis of the ring.

Abstract: A plurality of conductive rings are arranged projecting relatively to a fixed component. Such ring comprises two thin conductive circles separated by an electrically insulating material. Blades fixed to pins make sliding contact with the outer and inner circles. The blades are advantageously staggered relatively to one another. It is thus possible to obtain a very compact electrical contact device between two concentric members capable of undergoing relative rotation.

Abstract: A double contact, crossed roller or ball bearing assembly with roller paths inserted in supports made from another material in which each support has a single groove per row for balls or roller members and has mounted by deformation therein a single open ring formed from a bearing steel section having two enlarged portions joined by a thinner axial rib. The two bearing surfaces of each foller path are machined in the two enlarged portions of each ring.

Abstract: Snappable separators adapted to be connected together by means of a ring in order to form a cage for rolling bearing elements.Cylindrical nesting surfaces -- one convex 9 and one concave 10 -- are intended to produce the contacts between adjacent separators on the side on which the axis of the cage of the bearing is located.An assembling ring 8 surrounds all of the separators at the periphery of the cage which is thus formed.

Abstract: A bearing having two rows of cylindrical oblique contact rollers, each row being located in an annular space defined between two annular monobloc race members, the annular spaces containing surfaces which are loaded by and form tracks for the rollers and other surfaces which are non-loaded, one of the race members having a filling orifice which extends into one of the annular spaces through one of the non-loaded surfaces and through which the rollers with or without a cage can be inserted into the space.

Abstract: A roller cage for a roller bearing assembly is made from first and second apertured separators alternately interlocked in one another. Each apertured separator has a housing provided with two apertures and a roller adapted to be received in the housing through one of the apertures where it is resiliently encased. Each housing is symmetrical about the axis of revolution of the roller and has a symmetrical center at the mid height of the axis of symmetry. The first and second separators each have two part spherical surfaces symmetrical about a plane of symmetry containing the axis of the housing and the axis of the cage with the part spherical surfaces on the first separator being convex and those of the second separator being concave. The radius of curvature of the convex surfaces is equal to the radius of the concave surface so that the two separators can interlock with each other.
