The present invention concerns a rolling body cage for a linear guide or telescopic rail having rail elements which are displaceable relative to each other, wherein the rolling body cage has at least one bottom portion extending in a longitudinal direction of the rolling body cage, side wall portions which are arranged parallel and which extend on mutually opposite sides of the bottom portion substantially perpendicularly therefrom and in which there are provided rolling body holding recesses for receiving and holding rolling bodies between the raceways of rail elements and at at least a first end of the rolling body cage a connecting bridge which extends between the side wall portions substantially perpendicularly thereto, wherein the bottom portion, the side wall portions and the connecting bridge are produced in one piece from a first plastic. It has been found that both abutment of the inner rail against the rolling body cage and also abutment of the rolling body cage against the end abutment of the outer rail can generate noise which is perceived to be annoying. Therefore an object of the present invention is to further reduce those abutment noises. To attain that object it is proposed according to the invention that a rolling body cage of the kind set forth in the opening part of this specification is provided, in which the connecting bridge at least on two mutually opposite end faces is surrounded by a damping element comprising a second plastic, wherein the second plastic is softer than the first plastic.

A bearing cage assembly including two different cage halves formed from different materials is disclosed. The first cage half includes a first rim and a first plurality of arms extending from the first rim. The second cage half includes a second rim and a second plurality of arms extending from the second rim. The first cage half and the second cage half are fastened to each other via engagement between a plurality of first retainers of the first cage half with the plurality of second retainers of the second cage half.

A bearing cage assembly is disclosed herein that includes a first cage half formed as a plastic cage and a second cage half formed as a metal shell. The first cage half includes a first base rim and a first plurality of arms extending axially from the first base rim. The second cage half includes a second base rim and a second plurality of arms extending axially from the second base rim. The second plurality of arms are each formed by a first flange and a second flange. The first flange and the second flange are spaced apart from each other in a radial direction to define a receptacle dimensioned to receive a respective one of the first plurality of arms. Free ends of the first flange and the second flange are crimped over to retain the first cage half with the second cage half.

A bearing cage assembly is disclosed. The assembly includes a stiffening ring formed from a first material, and a cage formed from a second material that is different than the first material. The cage includes a plurality of arms extending axially away from a base rim. The plurality of arms define a plurality of rolling element pockets therebetween. Each of the plurality of arms defines a slot dimensioned to receive a portion of the stiffening ring, such that the stiffening ring is secured to the cage via engagement within the slots of the plurality of arms.

The present application discloses a bearing structural member, a support, a joint assembly and a tube section assembly, wherein the maximum counter force provided by the bearing structural member under an external load is an own designed threshold value, namely when the external load is greater than the designed threshold value of the bearing structural member, the bearing structural member deforms, and provides a counter force equal to the designed threshold value; the support includes at least one bearing structural member; and the joint assembly and the tube section assembly are both equipped with the support. When the external load is not high and is less than the designed threshold value, the bearing structural member may effectively suppress the deformation just like a rigid structural member; when the external load exceeds the designed threshold value, the bearing structural member may deform, and provide a stable counter supporting force less than the external load. The bearing structural member may be applied to the support, the joint assembly and the tube section assembly, plays a role in protecting the structures or key structural components, and may be widely applied to the fields of design of bridges, design of building structures, design of tunnels and the like.
