Abstract
(EN)
A bearing element for a bearing assembly has a body of polycrystalline diamond (PCD) material having a bearing contact surface, and a substrate bonded to the body of PCD material along an interface and having a free end surface. The substrate has a through-bore extending longitudinally therethrough, the body of PCD material having a portion extending through the through-bore in the substrate to at least the free end surface thereof, the substrate extending around the peripheral side edge of the portion of PCD material extending therethrough.
(FR)
Un élément de palier pour un ensemble palier comprend un corps en diamant polycristallin (PCD) ayant une surface de contact de palier, et un substrat lié au corps en PCD le long d'une interface et ayant une surface d'extrémité libre. Le substrat a un trou traversant s'étendant longitudinalement à travers celui-ci, le corps en PCD ayant une partie s'étendant à travers le trou traversant dans le substrat jusqu'à au moins la surface d'extrémité libre de celui-ci, le substrat s'étendant autour du bord latéral périphérique de la partie en PCD s'étendant au travers de celui-ci.
