ABSTRACT:
In a centrifugal casting machine, the mould carries a ring having a groove defining two spaced-apart annular non-axially extending bearing surfaces. The fixed frame of the machine carries a fixed journal perpendicular to the axis of rotation of the mould and contained in the plane containing the axis of rotation of the mould. A lever perpendicular to the journal is pivotably mounted on the journal and carries two support rollers freely rotatable on the lever. The axes of the journal and the support rollers are in the same plane and parallel to each other. The rollers taper to the axis of rotation of the mould and the two annular surfaces have the same taper as the rollers. The axial distance between the two annular surfaces of the ring allows the lever to pivot about the journal so that both rollers are always in contact with one of the annular bearing surfaces.
