A device for stabilizing pressure inside a gear's housing or a wheel's hub includes a bladder, and a conduit coupled to the bladder and coupleable to a volume containing a lubricant. The bladder includes a chamber having a volume, and is configured such that the chamber's volume increases as a fluid enters the chamber, and decreases as fluid leaves the chamber. The conduit includes a first end positionable adjacent the lubricant containing volume, a second end coupled with the bladder, and a passage between the first and second ends, and is configured to hold fluid disposed in the passage and direct the fluid between the first and second ends. When the conduit is coupled to the lubricant containing volume, the volume of the bladder's chamber, the passage of the conduit and the lubricant containing volume are isolated from the ambient environment.

A two-piece seal assembly includes first and second seal subassemblies, each shaped as a semicircular ring. The first seal subassembly has a first stator subassembly and a first rotor subassembly that cooperate to form a first semicircular segment of a labyrinth. The second seal subassembly has a second stator subassembly and a second rotor subassembly that cooperate to form a second semicircular segment of the labyrinth. The first and second stator subassemblies, when affixed to each other, form a ring-shaped stator that encircles a rotation axis. The first and second rotor subassemblies, when affixed to each other, form a ring-shaped rotor that encircles the rotation axis and can rotate about the rotation axis relative to the stator. When the first and second seal subassemblies are affixed to each other, the first and second semicircular segments meet such that the labyrinth encircles the rotation axis.

A rim sealing system comprising: a circumferentially elongated rim strip having a radially outwardly facing outboard surface, a radially inwardly facing inboard surface, a first lateral edge and a second lateral edge laterally spaced from the first lateral edge; a rim to receive the circumferentially elongated rim strip, where the rim includes a radially outwardly projecting first bead flange, a radially outwardly projecting second bead flange laterally spaced from the first bead flange, and a radially outwardly facing tire bed surface positioned laterally between the first bead flange and the second bead flange, and where the inboard surface of the rim strip circumscribes the tire bed surface; where the rim strip includes an overall lateral width between the first lateral edge and the second lateral edge and a radial thickness between the outboard surface and the inboard surface; and where the radial thickness is variable across the lateral width to include a first lateral region having a first radial thickness and a second lateral region having a second radial thickness, where the first radial thickness is thicker than the second radial thickness. A rim sealing strip comprising: a circumferentially elongated rim strip having a radially outwardly facing outboard surface, a radially inwardly facing inboard surface, a first lateral edge and a second lateral edge laterally spaced from the first lateral edge; where the rim strip includes an overall lateral width between the first lateral edge and the second lateral edge and a radial thickness between the outboard surface and the inboard surface; and where the rim strip includes a first lateral region and a second lateral region laterally adjoining the first lateral region; and where the material stiffness of the first lateral region has greater stiffness than the material stiffness of the second lateral region. A rim comprising: a rim, the rim comprising: a radially outwardly facing tire bed surfa

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).

A wheel hub unit provided with a radially outer ring, which is stationary during use; a radially inner ring, which is rotating during use; at least one row of rolling elements interposed between the radially outer ring and the radially inner ring; and a sealing assembly, which is interposed between the radially outer ring and the radially inner ring. The sealing assembly defines, cooperating with the radially outer ring or with the radially inner ring, a shield of at least one labyrinth seal. The labyrinth seal does not have a circumferential symmetry, but comprises an upper portion and a lower portion with respect to an axis of symmetry (A) of the wheel hub unit and is provided with an angular interruption of the shield formed on its lower portion corresponding to the lower side of the wheel hub unit so as to increase an outflow section thereof from the said labyrinth seal. Thereby, facilitating gravity drainage of contaminants present inside the sealing assembly.
