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.

Merkel V-packings are used for sealing piston rods, plungers and in exceptional cases of pistons. With their robust design they are very suitable for use in highly demanding, heavy and horizontal compressors, particularly if the plungers are subject to large side forces. V-packings can even be used if piston rods or plungers cannot be correctly used because of wear. V-packing in connection with fabric pressure and back-up rings are used primarily in heavy-duty hydraulics because they can easily be tightened at any time and their robust design. V-packing rings are supplied open for nominal diameter up to an inside diameter of 400 mm. For larger diameters the rings are over dimensioned in length, and they must be precisely fitted during fitting into the compression packing. If required endless rings can also be supplied. If no information on the version, the fluid or temperature is given, B/B (see Operating parameters range table) is delivered as the standard version.
There are several ways to seal a hydraulic cylinder, and using different types of seals can help prevent leaks and ensure proper operation of the cylinder. Here are a few ideas:
It's important to use the appropriate seals and other components for your specific hydraulic cylinder to ensure proper sealing and operation.
There are several ways to seal a hydraulic cylinder:
1. Piston seal: This is a sealing element that prevents fluid from leaking past the piston as it moves within the cylinder. Some synonyms for this component include: O-ring, packing, seal ring.
2. Rod seal: This is a sealing element that prevents fluid from leaking past the rod as it extends and retracts within the cylinder. Some synonyms for this component include: lip seal, scraper seal, dynamic seal.
3. Wiper: This is a component that removes contaminants and debris from the rod as it extends and retracts within the cylinder. Some synonyms for this component include: dust seal, dirt scraper, rod protector.
4. Guide band: This is a component that helps guide the rod as it extends and retracts within the cylinder. Some synonyms for this component include: guide ring, guide bushing, rod guide.
It's important to properly seal a hydraulic cylinder to ensure the system operates efficiently and effectively. Using high-quality sealing elements and regularly maintaining and replacing them as needed can help prolong the life of the cylinder and prevent costly repairs.
Piston seal: O-ring, gasket, packing, sealing ring, sealing element Rod seal: Lip seal, radial seal, dynamic seal, reciprocating seal, shaft seal Wiper: Scraper, cleaner, wipeless seal, dust seal, dirt seal Guide band: Guide ring, guide bushing, guide element, guiding element, guiding ring
A slydring is a type of hydraulic seal specifically designed for use in high-pressure, high-temperature environments. It is made of a special material called PTFE (polytetrafluoroethylene) that is resistant to wear and abrasion, and it is used to seal the gap between a piston rod and a cylinder bore in a hydraulic cylinder.
A glydring is a type of hydraulic seal that is similar to a slydring in that it is made of PTFE and is used in high-pressure, high-temperature environments. However, a glydring is designed to seal the gap between two moving parts in a hydraulic system, such as between a pump and a motor or between two rotating shafts.
A slydring is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system. It is typically made of a flexible material such as rubber or polyurethane and is designed to provide a low-friction seal that prevents leakage of fluid or contaminants from the system.
A glydring is a type of seal that is similar to a slydring but is made of a material that is resistant to high temperatures and is specifically designed for use in high-temperature applications. It is often used to seal gaps between moving and stationary components in high-temperature hydraulic systems or in other high-temperature environments.
A single acting piston seal is a type of seal that is used in a hydraulic cylinder that only applies pressure in one direction. This type of seal is typically used in applications where the cylinder only needs to extend or retract, such as in a dump truck hoist or a car jack.
A double acting piston seal, on the other hand, is a type of seal that is used in a hydraulic cylinder that applies pressure in both directions. This type of seal is typically used in applications where the cylinder needs to extend and retract, such as in a hydraulic press or a hydraulic lift.
An example of a single acting piston seal might be a rubber o-ring that is used to seal the gap between the cylinder and the piston in a single acting hydraulic cylinder. An example of a double acting piston seal might be a pair of u-shaped seals that are used to seal the gap between the cylinder and the piston in a double acting hydraulic cylinder.
A single acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to only one side of the piston. This type of seal is typically used in applications where the piston only needs to move in one direction. An example of a single acting piston seal is a seal used in a hydraulic jack or a hydraulic press.
A double acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to both sides of the piston. This type of seal is typically used in applications where the piston needs to move in both directions. An example of a double acting piston seal is a seal used in a hydraulic cylinder on a bulldozer or a hydraulic cylinder on a forklift.
