  • Patent number: 3975067
    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.
    Type: Grant

  • Patent number: 3966284
    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.

  • Patent number: 3948578
    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.

  • Patent number: 3938866
    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.
