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 lip seal with a projecting lip portion () extends along the longitudinal seal section and a second lip seal with a projecting lip portion () extends along the transverse seal section. A height of the projecting lip portion () of the first lip seal oscillates in a wave shape in the adjustment direction. 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.
