<p>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).</p> |
