A device includes a bottom support cover, a top bracing cover, an annular passage being defined between the covers, at least one bearing disposed between the covers, and at least one annular seal. The seal provides a fixing portion secured by mechanical link to a first cover out of the bottom support cover and the top bracing cover and at least one sealing lip extending towards the second cover in such a way that a free end of the lip comes to bear via a sliding-contact portion with a sealing surface of the second cover. The second cover is provided with an annular protection rim protruding from the sealing surface, the protection rim being offset towards the annular passage facing the portion of contact of the free end of the sealing lip with the sealing surface.

A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a steerable rear wheel assembly, a steerable front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

The invention relates to an assembly comprising a bushing with a center line L, having an inner sleeve with a mounting bore, an outer sleeve and an elastomeric spring member extending along a height H along the center line L. In one embodiment, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve are on each side of the center line L substantially parallel. On at least one side of the longitudinal center line L, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve extend at an angle to the center line L. An outer surface of the outer sleeve is substantially parallel to the center line L along the height H. Another embodiment of an assembly according to the invention comprises a bushing with a mounting bore that extends at an angle to the center line L. The bushing according to the invention is compact, can be easily manufactured and assembled, take up a high load and can be adjusted to the direction along which forces act on the bushing.
