A rotation induction device for a vehicle includes: an upper case having a piston rod disposed therethrough; a lower case disposed adjacent to the upper case and having the piston rod disposed therethrough; a center plate between the upper case and the lower case such that the piston rod passes through the center plate, and to induce rotation of one or both of the upper case and the lower case; and a lubricant retention part disposed on the lower case, and to store a lubricant therein.

A flexible double lipped annular seal includes an anchor segment at a radially outermost portion thereof and having a pocket formed therein. The annular seal includes a branch segment extending axially outward and radially inward from the first leg at an angle. A first lip seal and a second lip seal extend radially inward from the branch segment and have a gap therebetween. The branch segment terminates in a stub segment. The annular seal includes a metallic shield secured to the annular seal and a portion of which seats in the pocket.

Provided are: a slide bearing configured so that degradation in sliding performance caused by the entry of dust, muddy water, etc. can be prevented at low cost; and a strut-type suspension using the slide bearing. A slide bearing (1) is provided with: an upper case (2); a lower case (3) joined to the upper case (2) in a pivotal manner and forming an annular space (5) between the upper case (2) and the lower case (3); and an annular center plate (4) disposed in the annular space (5). An annular lip (43) is formed integrally at the outer peripheral edge (423) of the flange (42) of the center plate (4). The lip (43) is in contact, while deflecting, with an annular protrusion (252) formed in an annular groove (24) in the upper case (2) and covers a thrust bearing surface (422) and a thrust supporting surface (251).

A landing leg assembly for a heavy duty commercial vehicle includes a first leg member defining an interior space, a second leg member telescopingly engaging the first leg member and movable between a retracted position and an extended position with respect to the first leg member, a gear assembly at least partially located within the interior space of the first leg member and operably coupled to the second leg member and configured to receive an input from a user to move the first leg member between the retracted and extended positions, the gear assembly including a shaft member and a gear member fixed for rotation with the shaft member, and an integral, single-piece bearing member including a bore that rotatably receives the shaft member, wherein the bearing member comprises a powdered metal and is directly welded to the first leg member.

A cleaning apparatus has a hollow input shaft connectable to a hydraulic pressure source, is received in a first housing part and has a fluid conduit, with at least one lateral or axial input and at least one lateral output. At least one hollow output shaft is fluidically coupled to the hollow input shaft, received in a second housing part, and has a fluid channel, with at least one lateral input and at least one lateral or axial output. The hollow input shaft and/or the hollow output shaft is/are mounted rotatably about the longitudinal axis thereof relative to the relevant housing part. A first chamber is at least between the input or output of the hollow input shaft or the input of the at least one hollow output shaft and an interior lateral surface of a sealing sleeve. The sealing sleeve is fixed in a stationary and non-rotatable manner on the relevant housing part and arranged surrounding a portion of the hollow input or output shaft. Regions of the interior lateral surface of the sealing sleeve extending axially from the first chamber form a gap seal with the exterior lateral surface of the hollow input or output shaft.

A sealing apparatus which is capable of preventing static leakage of a target to be sealed without increasing sliding resistance with respect to a shaft, and a surface processing method of a disk member of the sealing apparatus which is capable of processing a surface of the disk member, such as a slinger, provided at the sealing apparatus. A surface processing method of a disk member of a sealing apparatus for forming a plurality of fine spiral grooves on a surface of the disk member provided at the sealing apparatus has a grinding member having a plurality of fine projections that is moved to an outer edge side while the grinding member is pressed against the surface of the disk member which relatively rotates around an axis, and the sealing apparatus includes a slinger at which a plurality of fine spiral grooves are randomly formed on another side surface of a flange portion.
