A seal (1) for a hydrostatic linear guide with a given adjustment direction (5), with a longitudinal seal section (7, 7′) extending essentially parallel to the adjustment direction (5), and with a transverse seal section (8, 8′) extending essentially transverse to the adjustment direction (5), wherein a first lip seal with a projecting lip portion (12) extends along the longitudinal seal section and a second lip seal with a projecting lip portion (14) extends along the transverse seal section. A height of the projecting lip portion (12) of the first lip seal oscillates in a wave shape in the adjustment direction. With such a seal (1), both a high degree of static oil tightness and also a high degree of dynamic oil tightness are achieved for a hydrostatic linear guide.
Seal for a hydrostatic linear guide with a given adjustment direction, comprising a longitudinal seal section extending essentially parallel to the adjustment direction, and with a transverse seal section extending essentially transverse to the adjustment direction 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, and a height of the projecting lip portion of the first lip seal oscillates in a wave shape in the adjustment direction.
A carrier body of a hydrostatic linear guide having a given adjustment direction comprising a central recess for holding a longitudinal rail, a seal is arranged along an edge surrounding the recess, the seal comprising a longitudinal seal section extending essentially parallel to the adjustment direction, and with a transverse seal section extending essentially transverse to the adjustment direction 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, and a height of the projecting lip portion of the first lip seal oscillates in a wave shape in the adjustment direction.
