Piston Seals

Hydraulic Seals-Rod Seals Rod U-seal   UR   BS

Description : 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 under the seal by the secondary lip.

BS is mainly designed for the sealing of piston rods and plungers in heavy duty applications mobile and stationary hydraulics.


-unusually high wear resistance.

-Insensibility against shock loads and pressure peaks.

-High resistance against extrusion.

-Low compression set.

-Suitable for hardest 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.
