Abstract
A wheel construction having bearing means therein defining an axis of rotation. The bearing means is housed in an elastomeric sleeve having an elastic compressibility characteristic. A pair of identically shaped metallic stampings, each having a central cylindrical shell part axially aligned with the other, is provided for housing the bearing structure therein. Each of the stampings has a surface portion intermediate the central cylindrical shell part and the outer periphery thereof, which are coextensive with a central plane through the wheel construction perpendicular to the axis of rotation. The axially aligned cylindrical shell parts engage at least a portion of the elastomeric sleeve of the bearing structure. An annulus of moldable synthetic resin material is fixedly secured to the peripheral surface of the pair of metallic stampings to hold the cylindrical shell part and the surface portions in axial alignment. The annulus has an elastically flexible characteristic to thereby permit the pair of stampings to shift radially relative to one another while maintaining said surface portions in sliding engagement with one another.
