Freudenberg Sealing Technologies Piston Seals (Hydraulic) Hydraulics

The piston seals of Freudenberg Sealing Technologies can be used in a variety of modern sealing systems: Their task is to seal the piston reliably against the cylinder tube and guarantee its movement efficiently with minimum friction and no drift. The piston seals persuade due to their durability and high functionality. They are suitable for all kinds of requirements.

The rotary/swivel seals of Freudenberg Sealing Technologies are characterised by their high performance - even under a static load. They are particularly suitable for use in hydraulic joints and withstand high pressure loads, even in conjunction with translational motion and the related operating temperatures.

Piston Guide Rings

The task of guides is to guide the rods and pistons of pneumatic and hydraulic cylinders and prevent them from coming into direct metallic contact with the cylinder housing. The guides of Freudenberg Sealing Technologies are able to take up high shearing forces even in case of a short guiding distance and, at the same time, low frictional losses. They are also available as guide rings. Depending on the load, various materials may be used: PTFE, polyamide and laminated fabric. For every type of cylinder and application, Freudenberg Sealing Technologies offers the right guide with maximum reliability and durability from this portfolio:

In pneumatic and hydraulic cylinders, wipers protect the inside of the cylinder against the penetration of dirt during the retraction of the rod. For every type of cylinder and application, Freudenberg Sealing Technologies offers the right wiper with maximum reliability and durability: individual wipers with or without metal reinforcement, as well as double wipers with or without pressure relief.

The roof flange sets of Freudenberg Sealing Technologies consist of a pressure ring, one or more collars and a support ring: The multi-part sealing sets are particularly well-suited for robust areas of application, such as the supply of spare parts for old systems. The roof flange sets persuade due to their long service lives. The sealing sets can be used for pistons that are pressurised on one side or on two sides - back to back.

The rod seals of Freudenberg Sealing Technologies persuade with their durability and high efficiency. They are primarily used in pneumatic and hydraulic cylinders. Their task is to seal the retracting and extending cylinder rod , thereby preventing the pressurised operating medium from escaping from the cylinder while protecting the cylinder from impurities. The rod seals are available for every type of cylinder and application.
