BS (Rod Seals)

The PDF Ultrathan® Rod Seal Profile BS is a lip seal with a secondary sealing lip and tight fit at the outer diameter. Wear and dry run are largely prevented by the additional lubricant retained within the gap created by the secondary lip. In some cases this second sealing lip may even act as substitute for a costly tandem-arrangement when complete sealing under certain working conditions can only be achieved by two seals placed one behind the other in separate housings. The Rod Seal Profile BS is o be used when the physical properties of normal or fabric-reinforced elastomers are insufficient.

The BS offers:

• Unusually high abrasive resistance.

• Insensitive to intermittent loads and pressure peaks

• High extrusion resistance

• Low Compression Set

• Suitable for arduous working conditions

• Sufficient lubrication due to pressure medium between the sealing lips

• Increased sealing performance at Zero pressure

• Air penetration from outside is largely prevented

• Easy installation

Hydraulic Application:

• Working Pressure: =400 bar

• Working Temperature: -35°C to 110°C (-31°F to 230°F)

• Surface Speed: =0.5 m/s
