A guide carriage includes a main body, a separate track element connected to the main body, at least one carriage track, at least one deformation sensor, an evaluating device, and at least one row of endlessly revolving roller elements that roll off on an associated carriage track in a load-transmitting manner. The carriage track extends parallel to a longitudinal axis, and is positioned on the track element. The track element has at least one self-supporting section not supported on the main body and located at one end of the track element along the direction of the longitudinal axis. The at least one deformation sensor is connected to the evaluating device, positioned in a region of a respective self-supporting section of the track element, and configured to measure a deformation of the respective one of the at least one self-supporting sections of the track element.

A pinion needle roller bearing post for use during pinion gear carrier assembly includes a solid cylindrical post having a longitudinal surface wall extending between a first end and a second end. At least one radially recessed channel is disposed in the longitudinal surface and extends substantially between the first end and the second end and a spring biased needle roller is disposed within the at least one radially recessed channel that operates to prevent needle roller bearing skew during pinion gear carrier assembly.

A system includes a device, a support structure, and a flexure bearing configured to connect the device to the support structure. The flexure bearing includes an outer hub and an inner hub, where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets of flexure arms connecting the outer hub and the inner hub, where each set of flexure arms includes symmetric flexure arms. The flexure bearing further includes multiple bridges, where each bridge connects one of the flexure arms in one set of flexure arms to one of the flexure arms in an adjacent set of flexure 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.

The present disclosure relates to bearings, guide sleeves and head restraint assemblies for automobiles.

A bearing for guiding a first guided piece includes a first bearing surface with respect to a second bearing surface fixedly attached to a second guided piece. At least one first intermediate piece is interposed between the first bearing surface and the first guided piece and at least one first automatic release assembly for i) in a first assembly state, fixedly attaching the at least one first intermediate piece and the first guided piece for guidance forces which are lower than a triggering value, and ii) in a release state, permitting a relative displacement of the first guided piece with respect to the at least one first intermediate piece, at least in one displacement orientation, for guidance forces which are greater than the triggering value of the first assembly.

An earth-boring tool for drilling a subterranean formation includes a bit body having a central axis and a cavity extending into the bit body from an outer surface thereof. A bearing element assembly may be mounted within the cavity. The bearing element assembly comprises a lower retaining member, an upper retaining member mounted over to the lower retaining member, the upper retaining member comprising an aperture formed therethrough, and a spherical bearing element disposed over the lower retaining member and extending through the aperture formed through the upper retaining member. The spherical bearing element is rotatable about three axes of rotation within the lower retaining member and the upper retaining member.

A clip for providing a sliding force towards a movable substrate, the clip including at least one strip, where the at least one strip comprises a first axial end and a second axial end and an arcuate shape between the first axial end and the second axial end; where the at least one strip is a metal strip including a sliding layer at an outbound side.

A slide rail assembly for mounting a chassis to a rack is provided. The chassis has multiple mounting members on a lateral side. The slide rail assembly is mounted on the rack by two brackets and includes first and second rails, a first auxiliary supporting member, and multiple reinforcing segments. The first rail has first and second sides, wherein the first side has a concave space. The second rail can be displaced with respect to the first rail and has an inner side and an outer side. The first auxiliary supporting member is mounted in the concave space of the first side of the first rail. The reinforcing segments are fixedly mounted on the inner side of the second rail.
