Abstract
A seal () for a hydrostatic linear guide with a given adjustment direction (), with a longitudinal seal section (') extending essentially parallel to the adjustment direction (), and with a transverse seal section (′) extending essentially transverse to the adjustment direction (), wherein a first sealing lip () extends along the longitudinal seal section (′) and a second sealing lip () extends along the transverse seal section (′), and wherein the longitudinal seal section (′) and the transverse seal section (′) are connected to each other. Here it is provided that the first sealing lip () and the second sealing lip () merge into each other with a constant curvature (). With such a seal (), both a high degree of static oil tightness and also a high degree of dynamic oil tightness are achieved for a hydrostatic linear guide.
