A support according to claim 1, characterized in that the ceramic element is placed in a recess of the metal body and is retained in said recess by one or more bonding or brazing points formed on or close to a top edge of the recess.12. A support according to claim 1, characterized in that the ceramic example is merely placed in a recess of the metal body.13. A support according to claim 1, characterized in that the ceramic element is set in the metal body with clearance allowing the ceramic element and the metal body to expand freely.14. A support according to claim 1, characterized in that the ceramic element is set in said base.15. A support according to claim 14, characterized in that the ceramic element comprises an annular part having an axis of symmetry (AS1) in common with the guide element.16. A support according to claim 14, characterized in that the support surface or support surface portion is shaped to provide contact at one or a plurality only of discrete points with an annular part when such an annular part rests, at least in part, flat on the support.17. A support according to claim 14, characterized in that the support surface or support surface portion is inclined, or includes an inclined portion, so as to prevent lateral movement of the part when it rests, at least in part, flat on the support.18. A support according to claim 14, characterized in that the support surface or support surface portion is frustoconical in shape.19. A support according to claim 14, characterized in that the support surface or support surface portion is in the form of part of a spherical surface.20. A support according to claim 1, characterized in that the ceramic element is set in the end portion of the guide element.21. A support according to claim 1, characterized in that the metal body comprises a generally pawn-shaped peg.22.
