Abstract
A linear motion bearing assembly includes a carriage having a bearing track, a fluid inlet port and a fluid supply passage interconnecting the fluid inlet port and the bearing track. The bearing track has a load bearing portion, a return portion and a pair of turnarounds interconnecting the load bearing portion and the return portion. The carriage is supported for linear movement on a rail. A plurality of rolling elements are positioned in the bearing track and a pressurized hydrostatic fluid supply is connected to the fluid inlet port for supplying hydrostatic fluid under pressure to the bearing track.
