Abstract:
A roller washer bearing for enabling alternating unidirectional movement of a top plate relative to a bottom plate fastened together by a fastening means extending through the roller washer bearing and providing a loading force, the washer comprising,a plurality of rods unidirectionally aligned within a horizontal plane parallel to the top and bottom plates, the rods extending horizontally and in parallel in the horizontal plane parallel to the top plate and the bottom plate while supporting the loading force, the rods being elongated rollers rolling back and forth in alternating unidirectional motion parallel to the horizontal plane,top surface means for confining the rods in the horizontal plane and for buttressing the top plate,bottom surface means for confining the rods in the horizontal plane and for buttressing the bottom plate, andan aperture extending through the top surface means and bottom surface means for receiving the fastening means, the aperture being larger than the fastening means for providing space around the fastening means for enabling the fastening means to move relative to the top plates as the rods roll back and forth as the top plate moves back and forth in alternating unidirectional movement relative to the bottom plate.
