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.
The requirements are high. Freedom from leakage is not only a "must" for drive shafts in shipping. Cleanliness is also of utmost importance in the paper industry with its high-speed rolls.
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.
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.
Rod Seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod.
Piston Seals in pneumatic and hydraulic cylinders have the task of sealing the piston against the cylinder tube.
Wipers in pneumatic and hydraulic cylinders protect the interior of the cylinder from the penetration of external contaminants when the rod is retracted.
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.
Premium quality oil seals for dynamic, static, reciprocating and rotational applications for the world’s leading automotive suppliers and OEMs.
The Damp & Seal damper seal from Freudenberg Sealing Technologies combines three functions into a single component.
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.
