Pivot bearing
First Claim
1. Pivot bearing comprisinga mounting rod having an axis,an annular rubber cushion mounted coaxially about said mounting rod,a annular body mounted on said annular rubber cushion and having a spherical outside surface,a guiding ring having a spherical inside surface which cooperates with said spherical outside surface of said annular body to permit rotational movement, and an outside surface,a case coaxially surrounding said guiding ring, said case comprising a first case portion and a second case portion, each portion comprising a tubular portion fit over the outside surface of the guiding ring, an abutment flange which limits rotational movement of the mounting rod in the guiding ring, and an intermediate portion extending radially inward form said tubular portion to said abutment flange, each said intermediate portion having a concave surface facing said rubber cushion, andbellows means extending between said case and said mounting rod.

Abstract
An annular body (2) having a spherical outside surface is fixed coaxially on an annular rubber cushion (3) which in turn is fixed coaxially on a mounting rod (10). A guiding ring (4) is supported inside a case (1) and has a spherical inside surface which cooperates with the spherical outside surface of the annular body to permit rotational movement. The case has axial abutments (6,7) which limit rotational movement and serve as fixing points for bellows which protect the joint.
