Dynamic Seals
Portfolio Freudenberg Sealing Technologies
Damp & Seal
The Damp & Seal damper seal from Freudenberg Sealing Technologies combines three functions into a single component.
Rod Seals
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 in pneumatic and hydraulic cylinders have the task of sealing the piston against the cylinder tube.
V-Ring Seals and Deflectors
V-Ring Seals and Deflectors must withstand a great deal. So Freudenberg Sealing Technologies had to come up with something special to meet heavy industry's often high expectations in this area.
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.
Wipers
Wipers in pneumatic and hydraulic cylinders protect the interior of the cylinder from the penetration of external contaminants when the rod is retracted.
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.
Radial Shaft Seals
While Freudenberg Sealing Technologies invented the Radial Shaft Seal, we haven't stood still. The Simmerring® continues to meet the ever-changing and demanding needs of our customers.
Rotary and Swivel Seals
It is the combination of operating conditions that put Rotary and Swivel Seals to the test. They must withstand pressure loads similar to those in hydraulic cylinders.
Static Seals
Portfolio Freudenberg Sealing Technologies
Cover Seals
Even if machine elements under pressure are firmly bolted to one another, there is still a so-called static seal gap that must be sealed.
Gaskets
Gaskets produced by Freudenberg Sealing Technologies are designed as an integral part of a sealed system.
O-Rings
Endless O-Rings with a circular cross-section: O-Rings are among the sealing classics par excellence.
Hydraulic Accumulators
Portfolio Freudenberg Sealing Technologies
Suspension Systems
With individualized load adjustments using hydropneumatic systems, Freudenberg Sealing Technologies has succeeded in significantly reducing the incidence of vibrations and shock forces.
Hydraulic Accumulators
Hydraulic Accumulators are a basic component of hydraulic systems. They support hydraulic functions in a broad range of applications: from construction machinery all the way to the auto industry.
Special sealing products
