Item Information

The BS Ultrathan® rod seal is a U-ring with interference fit on the outer diameter and a secondary sealing lip. It is extremely
wear-resistant, ensures reliable load holding performance and is suitable for high-pressure hydraulic applications. The additional
lip results in a larger deposit of lubrication film underneath the seal. This largely prevents dry running and higher wear, en
achieves longer service life. Due to its radial preloading, the secondary sealing lip reliably wipes off the liquid film even in
low pressure conditions or non-pressurized movement of the rod. For telescopic cylinders, we recommend the version with a 4-mm
profile width.

• Excellent sealing performance due to elongated contact area and multiple sealing lips.
• Exceptionally high static and dynamic sealing performance.
• Enhanced sealing performance in non-pressurized conditions.
• Penetration of air into the system is largely prevented.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Easier installation.
• Insensitive to pressure peaks.
• Improved lubrication due to pressure medium deposit in the dynamic contact area.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Dimensions according to ISO 5597.
• Short radial assembly depth.
• Installation in closed and undercut housings.
• Further dimensions of machined series with short lead times available.

Range of application:
Mainly for sealing piston rods and plungers in heavy-duty applications in mobile and stationary hydraulics. The range of
dimensions is primarily oriented to the requirements of ISO 5597 and ISO 3320 for housings and diameters.
