A linear motion bearing assembly includes a carriage (12) having a bearing track (14, 16), a fluid inlet port and a fluid supply passage interconnecting the fluid inlet port (40) and the bearing track (14, 16). The bearing track (14, 16) has a load bearing portion (22), a return portion (24) and a pair of turnarounds (26) interconnecting the load bearing portion (22) and the return portion (24). The carriage (12) is supported for linear movement on a rail (20). A plurality of rolling elements (18) are positioned in the bearing track (14, 16) and a pressurized hydrostatic fluid supply is connected to the fluid inlet port (40) for supplying hydrostatic fluid under pressure to the bearing track (14, 16).
L'invention concerne un ensemble de support à mouvement linéaire qui comporte un chariot (12) muni d'une voie de support (14, 16), d'un orifice d'entrée de liquide et d'un passage d'alimentation en liquide reliant entre eux l'orifice d'entrée de liquide (40) et la voie de support (14, 16). Celle-ci comporte une partie de support de charge (22), une partie de retour (24) et deux parties de retournement (26) reliant entre elles la partie de support de charge (22) et la partie de retour (24). Le chariot (12) est destiné à permette un mouvement linéaire sur un rail (20). Une pluralité de d'éléments roulants (18) sont disposés sur la voie de support (14, 16) et une source de fluide hydrostatique pressurisé est reliée à l'orifice d'entrée de liquide (40) de façon à alimenter la voie de support (14, 16) en fluide hydrostatique pressurisé.
