A castor includes a casing constituted by a part having at least one housing suitable for receiving a pivot defined on an axis, and a bearing defined on an axis perpendicular to the axis, at least one wheel suitable for running on a surface, a shaft mounted to co-operate in the bearing, the wheel being mounted in association with the shaft, the part being constituted by at least two portions and that are made respectively of two materials of different flexibilities, the portion presenting the greater flexibility being interposed between the housing and the axial orifice of the bearing so as to isolate the housing and the bearing from each other. The castors may be used with furniture or the like, in particular in a hospital setting, e.g. for beds, tables, walkers, and also for moving suitcases, baggage, or the like.
