A stabilizer includes: a stabilizer bar made of a pipe material; and a stabilizer link that couples the stabilizer bar and a suspension device. The stabilizer link includes a ball stud which includes a shaft portion inserted to and fixed in an opening end of the stabilizer bar and a ball portion formed at a leading end of the shaft portion, a housing which rotatably supports the ball portion, and a flexible dust cover which includes one end attached on the housing so as to be unmovable in a ball stud axis direction and the other end attached on at least either of the shaft portion and the stabilizer bar and which seals a space between the housing and the ball stud.

In a ball joint with a housing, a ball stud which includes a ball head mounted in the housing, and with a sealing bellows which includes a ring-shaped housing-side connecting region, it is provided that at the housing a ring-shaped channel is provided, in which the housing-side connecting region is accommodated, wherein the outer radius of the channel at the channel bottom is greater than the outer radius at the free edge of the channel, and on the housing-side connecting region of the sealing bellows at least one holding element made of a rigid material is provided, which in particular in a top view in longitudinal direction of the ball stud is at least partly covered by the free edge of the channel.

A radial ball joint (1, 50, 70) for a vehicle having a housing (2, 51) for holding a joint ball (11) of a ball stud (6) so that the ball stud can rotate and pivot. An upper bearing shell (7), made from a steel sheet, is arranged between an inside wall (10) of the housing (2, 51) and the joint ball (11). The upper bearing shell (7) is in contact with the joint ball (11) over a contact zone (21) to provide the joint ball (11) with a circumferential slide bearing between its equator (12) and its upper pole (13). The upper bearing shell (7) is in the form of an annular, circumferentially closed drawn component and has in the contact zone (21) with the joint ball (11). A number of lubrication grooves (14), pass through a wall (20) of the upper bearing shell (7), in an embossment manner.

A boot seal is detachably attached to a joint including: a drive link and link members; and a ball joint for linking them to be relatively rotatable or swivelable. The ball joint includes a ball shank having a shaft section fixed to the drive link and a ball section provided on one end of the shaft section and a holder that is fixed to an end section of each of the link members and that has a ball-receiving section for supporting the ball section in a state where the ball section is surrounded. A cover main body that covers the gap between the ball shank and the holder and that is formed of a flexible material includes through-holes through which the shaft section is made to pass, a slit that continuously extends between the through-holes, and a fastener opening and hermetically closing the slit along the entire length thereof.

A sealing bellows includes a casing. The casing includes a rubber-elastic material, which includes an edge region at the front side on both sides. A clamping ring for fastening the sealing bellows to a machine element is arranged in at least one of the edge regions. The clamping ring is formed by an annular disk which, viewed in the circumferential direction, has a meander-like configuration.

A seal includes an at least partially cylindrical annular body defining a radial direction, an axial direction, and a circumferential direction. The at least partially cylindrical annular body has a radially outer flange, a radially inner ring, and a resilient intermediate portion joining the radially outer flange to the radially inner ring. The radially outer flange defines a seal outer diameter and a flange axial thickness, and a ratio of the seal outer diameter to the flange axial thickness ranges from 14.0 to 15.0.

A boot with a body cavity that protects a moveable joint and retains lubricant associated with the joint is disclosed. The wall of the boot body includes a venting aperture that is protected by a surrounding barrier structure.

Provided are a ball joint and a dust cover that make it possible to suppress contact of a body portion of the dust cover with the vicinity of a flange portion of a ball stud. A dust cover integrally includes: a deformable bellows-shaped body portion made of an elastic body; a fixed portion made of an elastic body and provided on one end side of the body portion; and a sealing portion made of an elastic body and provided on the other end side of the body portion. The sealing portion includes: an inner peripheral sealing portion configured to be slidable on a part of a shank portion on the opposite side of the shank portion from a spherical portion with respect to a flange portion; and a cover portion that continuously covers, in an outer wall surface of the flange portion, a radially outward tip end portion and a part of a portion that decreases in diameter from the tip end portion toward the spherical portion side.

A dust cover for a ball joint is made up of a dust cover body made of a rubber elastic material and an annular plate member. In the dust cover body, a reinforcement ring is disposed in a stud mounting part, and an annular step is disposed on the inner peripheral side of the reinforcement ring. The plate member is made up of a plate body and an annular sealing part that is made of a rubber elastic material and is accommodated in the annular step. In the outer periphery of the plate body, a plurality of cut parts are formed, so that outer peripheral petal parts are formed between adjacent cut parts to be capable of being bent so as to be engaged with a knuckle groove.

A dust hoot for a moveable joint is provided. The dust boot includes a boot body disposed annularly about an axis and defining an interior cavity. The boot body has a housing opening at a first longitudinal end for attaching to a housing and a shank opening at a second longitudinal end opposite the first longitudinal end for sealingly engaging a shank portion of a ball stud of the ball and socket joint assembly. The boot body defines a plurality of longitudinal strengthening portions formed therein and extending longitudinally at an acute angle relative to the axis in a relaxed condition of the dust boot for resisting rotation of the dust boot in response to a rotation of the ball stud and for improving sealing of the dust boot with the shank portion of the ball stud.
