Abstract
A linear drive system has a guide rail and a transport device that is moveable along the guide rail. At least one tubular, flexible hollow body is positioned along the extension of the guide rail. The hollow body consists essentially of an elastomeric material and has a first and a second end. The at least one hollow body is loadable with a pressure medium from the first or the second end. At least one squeezing roller is rotatably connected to the transport device for forcing sealingly the at least one hollow body against a counter element. The guide rail consists essentially of a flexible elastomer.
