A linear guide device comprises a guide carriage having two end assemblies (,) arranged on the front ends of the guide carriage. The guide carriage is guided on a guide rail in the direction of the longitudinal axis of the device by means of rolling member loops (S,, S,). Within the end units (,) of the end assemblies (,) are provided parts of reversing guides for arcuate rows of rolling members of the rolling member loops (S,, S,). A lubricant path system (,) is provided within the guide carriage for satisfying a lubricant demand existing on the roll surfaces of the linear guide device. The lubricant path system includes, in a boundary region between an end unit (,) and a carriage main body, a lubricant oil supply capillary line (,) extending in circumferential direction of the guide rail and being formed of a suction member. The lubricant oil supply capillary line supplies lubricating oil to a licking region (,) irrespective of the existence of a pressure difference. The suction member (,) is in licking contact with the rolling members (,) of the rolling member loops (S,, S,) or with a bearing track of the guide rail in the licking region.

Linear guide device

The present invention relates to a linear guide arrangement comprising a guide rail with at least one axis and at least one guide carriage movable on the guide rail in the direction of the axis. The guide carriage runs on the guide rail with intermediacy of an endless rolling-element circuit. To this end, the guide carriage is designed with a guide carriage housing and with a carriage member made separately from the guide carriage housing and accommodated within the guide carriage housing. The guide carriage housing comprises at least one side panel adjacent to the rolling-element circuit and substantially parallel to the axial direction, as well as at least one end plate adjacent to the rolling-element circuit and substantially orthogonal to the axial direction. The bearing row of rolling elements runs on the carriage member.
