Patent ID: 8033580

Claim:
A linear guide device based on rolling-contact bearing technology for feeding working fluid to an assembly requiring working fluid, comprising: a working fluid selected from the group consisting of lubricating grease and lubricating oil; a plurality of fluid channels extending from a surface and including at least one fluid channel for feeding the working fluid, and at least one further fluid channel having a first section directly adjacent to the surface, a second section with a smaller diameter than that of said first section and, between the first section and the second section, having a first transition region with an annular surface, and at least one screw element screwed from the surface into the at least one further fluid channel for closing the latter, the at least one screw element having at least one sealing surface brought into sealing engagement with the annular surface, thereby forming a sealing effect without the use of additional sealing components, and wherein material of the at least one further fluid channel surrounding the annular surface is deformed in the second section by a pressure applied by the at least one screw element to the annular surface in the sense of reducing the volume of the at least one further fluid channel in the second section.
