摘要

Slide seal fora guide has a bearing bush of PTFE supported axially in the rod bearing, and in which the rod is slidably and/or rotatably located. Between teh bush and the rod bearing is an O-ring of elastic material under radial pressure. On the pressure side of the rod bearing, is a radial inner shoulder on which the presure side union surface of the O-ring is located. The bearing bush is additionally radially supported, and on its pressure side end is a peripheral section narrowing away inwards. On this the O-ring locates, and the bearing bush is movable axially on the O-ring.
