Dynamic Seals
Portfolio Freudenberg Sealing Technologies

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.

Damp & Seal
The Damp & Seal damper seal from Freudenberg Sealing Technologies combines three functions into a single component.

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.

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.

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

O-Rings
Endless O-Rings with a circular cross-section: O-Rings are among the sealing classics par excellence.

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.

Usit Rings
Designed in compliance with hygienic standards, the Freudenberg Sealing Technologies Hygienic Usit Ring with an elastomer bead is setting new purity benchmarks in the processing industry.

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
Portfolio Freudenberg Sealing Technologies

Diaphragms
Diaphragms may be used in an array of applications, including pumps, actuators, hydro-accumulators, valves, and regulators.

Stuffing Box Packings
So-called Stuffing Box Packings have been tried-and-tested for extremely high temperatures and chemical resistance in pump and valve applications.

Boots
Single- and multiple-convolution boots are protective seals for socket joints, ball joints and articulated shafts.

Precision Molded Parts
Precision Molded Parts consist wholly of elastomer materials and offer high precision, tight dimensional tolerances and high surface quality.

Encoder
Together with an appropriate sensor, Multipole Encoders provide for the precise measurement of speed and rotation angle for several applications in the automotive and general industry.
