Dynamic Seals

Dynamic seals are used in applications with motion between the hardware component and the sealing solution. The motion can be rotary, translatory, reciprocating or oscillating. Effective dynamic seals need to maintain a balance between the sealing force, minimize the friction and furthermore prevent leakage.

Overview of our Dynamic Sealing Solutions

Radial Shaft Seals

Simmerrings seal rotating shafts reliably and are used in millions of applications and a variety of equipment in general industry and the automotive sector.

Radiamatic Shaft Seals

Freudenberg Sealing Technologies has risen to these challenges and provides made-to-order shaft seal rings with the maximum leak tightness and reliability for a wide range of applications

Rotary and Swivel Seals

The high performance of Freudenberg Sealing Technologies Rotary and Swivel Seals is impressive – even under a static load.

U-Cups

U-rings are used to seal translational and rotating movements against aggressive media and pressures.

V-Ring Seals and Deflectors

V-Ring Seals and Deflectors from Freudenberg Sealing Technologies must withstand a great deal. Even during installation, they are stretched over the shaft and pushed against their subsequent seat.

Rod Seals

Rod Seals from Freudenberg Sealing Technologies perform multiple tasks. Rod Seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod.

Piston Seals

Piston seals are an indispensable component in many industrial applications in which hydraulic or pneumatic systems are used.

Wipers

In pneumatic and hydraulic cylinders, wipers protect the interior of the cylinder against external contaminant, as the cylinder rod is retracting.

Guide Rings

Guide Rings have the task of guiding the rods and pistons of pneumatic and hydraulic cylinders and preventing direct metallic contact with the cylinder housing.

Damper & Steering Seals

Oil seals for automotive and special purpose dampers and hydraulic and electric steering applications

Damp & Seal

The damping seal from Freudenberg Sealing Technologies combines the functions of what would normally be three components into a single part.

Valve Stem Seals

Freudenberg Sealing Technologies valve stem seals control leak rate for the life of the engine to assure correct guide lubrication while avoiding excessive oil consumption.
