The ball joint includes a metal ball stud which includes a ball section and a resin housing which rotatably supports the ball section of the ball stud. A limiting member configured to limit molding shrinkage of the housing is embedded in the housing at an interval with respect to an equatorial section of the ball section such that the limiting member is positioned to surround at least the equatorial section of the ball section.

The invention relates to a ball joint (5) including a ball stud (10) which has a spherical portion (12), two bearing shells (20) that are arranged on the spherical portion (12) such that there is a small gap (30) between them, and a housing (40) that is made from plastic in one piece and encloses the two bearing shells (20) such that they are urged against the spherical portion (12) by the housing (40).

A dry running mechanical ball joint seal includes a spherical element penetrated by a central passage and suspended between support rings that are pressed by springs against the spherical element and form a sliding dry seal therewith. A lip seal is located between the support rings and includes wipers pressed radially inward by a lip seal spring to form an additional seal with the spherical element. In embodiments directed to piping systems, a fluid is able to flow through the central passage. Other embodiments include a sliding rod directed through the central passage and sealed to the spherical element by a rod support within the central passage and also by at least one rod lip seal having a wiper pressed by a spring against the rod. The rod support can include a compressible packing material and/or a linear ball bearing sealed to the spherical element within the central passage.

The movable apparatus includes a holding body and a movable body. The holding body includes a first opening portion and an internal space, and is constituted of one part. The movable body includes an internal body and a first movable shaft portion. The internal body is stored in the internal space of the holding body, and has such a size that the internal body is prevented from exiting the first opening portion even if the first opening portion is elastically deformed. The first movable shaft portion is capable of being moved integrally with the internal body, and is exposed to outside of the holding body from inside of the holding body through the first opening portion.

The socket assembly includes a housing with an inner bore which extends along a central axis from a generally closed first end to an open second end. A ball portion of a ball stud is received in the inner bore of the housing. The ball stud also has a shank portion which projects out of the inner bore through the open second end. A backing bearing is disposed in the inner bore of the housing and has a curved bearing surface that is in slidable contact with the ball portion of the ball stud. The backing bearing is movable in a radial direction relative to the housing and includes a polymeric piece. The backing bearing further includes a reinforcement piece, which is made of metal, and the reinforcement piece is at least partially embedded within the polymeric piece to resist radial expansion of the polymeric piece.

A ball stud joint assembly for a motor grader may include a housing. The ball stud joint assembly may include a grease fitting to receive grease. The ball stud joint assembly may include a ball stud. The ball stud may include a head. The ball stud may include a stud. The stud may include a grease groove alignable to the grease fitting. The grease groove may include an annular portion and a linear portion. The stud and the housing may form a grease receptacle connected to the linear portion of the grease groove.

A boot for a ball socket assembly in an automotive pivoting and/or rotating socket having a flange with one or more thinned sections or gates adjacent a point of attachment to a socket housing that provides an effective seal against contaminants when lubricant is not being added with external pressure and also flexes when exposed to internal pressure allowing contaminated lubricant to escape from the socket. A ring is embedded in the flange with inwardly directed teeth flanking the thinned sections or gates for securing the boot to the socket housing.

A mobile robot (for example, a robot used for package deliveries, among other purposes) may include a mast with a visual indicator for providing visibility to drivers and pedestrians in the environment proximate to the mobile robot. The mast may produce a large moment arm, which may result in the mast being more likely to break off from the robot. To mitigate or prevent damage to any components of the mast and/or the mobile robot when such a breakage occurs, described herein is an omni directional breakage joint that is used to connect the mast to the mobile robot. The omni directional breakage joint comprises multiple ball and socket joints that provide structural support between the mast and the mobile robot, while simultaneously allowing for a certain movement freedom of the mast and allowing for the mast to easily be engaged and disengaged from the mobile robot without causing damage to any components.

A swivel hanger system includes an anchor member with an anchor head disposed at an end of the anchor member and an elongated body, where at least a portion of the elongated body is configured to be inserted into a support member when the system is connected with the support member. The system also includes a swivel member with an open end extending to a hollow interior of the swivel member, where the open end is configured to rotatably couple with the anchor head such that the anchor head is located within the hollow interior and the elongated body extends through the swivel member open end. The system further includes a stop structure to limit an insertion distance at which the anchor member is inserted into the support member.
