Rod Seals (Pneumatic)

NIPSL 310

 

The state-of-the-art pneumatic seals of Freudenberg Sealing Technologies are used in dynamic applications and employ combined wiping/sealing elements due to the lower operating pressures in comparison with those arising in hydraulics. In connection with special materials, the use of the pneumatic seal therefore leads to the development of a high-performance sealing system with an excellent price/performance ratio.

Piston Seals (Pneumatic)

NAP210

The pneumatic piston seals of Freudenberg Sealing Technologie seal the piston reliably against the cylinder tube and guarantee its movement efficiently with minimum friction and no drift. They are used in a variety of modern sealing systems. The pneumatic piston seals are adapted to the respective operating conditions and tasks and persuade due to their high functionality.

Damping Seals (Pneumatic)

AU DIP

The 3-in-1 Damp & Seal damper seal of Freudenberg Sealing Technologies combines the functions of three components in a single one, which extremely simplifies processes in the manufacturing of pneumatic cylinders, thereby relieving purchasing, warehouse and logistics departments. In addition, the 3-in-1 Damp & Seal damper seals offer excellent damping properties due to their specific design and highly loadable materials.

Standard Cylinder

A standard cylinder design is shown → Fig. The rod is guided in a bronze, plastic or brass bush and is fitted with a combined wiper and rod seal (Merkel Combination Seal AUNIPSL).

The piston is sealed using two pneumatic U-rings (Merkel U-Ring NAP 300, Merkel U-Ring NAP 310). A separate guide is installed between the U-rings.
