Hydraulic seals are devices that limit or prevent fluid escapes or any entrance of foreign materials within a hydraulic cylinder application. Commercial and industrial customers are able to order their hydraulic cylinder seals by size. These are designed to take care of high pressure dynamic applications. Seals are very much in demand in commercial and industrial machinery. They are important for the purpose of producing a path for fluid power to be converted to its linear motion.
They can be used for rotary and reciprocating motions as well. Hydraulic and pneumatic seals are characterized as and include piston seals, rod seals, rotary shaft seals, back up rings, buffer rings, oil and grease seals, static seals, symmetrical seals and cast iron piston rings and gaskets. Hydraulic seals are single and double acting. Single acting hydraulic seals will be used for one axial direction. Double acting hydraulic seals can be used in both directions in order to produce the reciprocating motions.
Hydraulic seals are made from a great variety of materials, among which include; nitrile, fluorocarbon rubber, nylon, bronze filled fluorocarbon rubber, polyurethane, silicone, nickel filled fluorocarbon rubber as well as glass filled fluorocarbon rubber. Hydraulic seals can also be molded out of fabric that has been reinforced from rubber or leather. To recap then. The seals are required to prevent any fluid solutions from escaping or entering a vessel. Depending on the commercial and industrial scale, seals can be prepared and ordered in different sizes.
Hydraulic seals have also been designed to take care of high pressure situations. The sealing devices can operate in different motions as the industrial purpose requires. And hydraulic seals, depending again on the commercial or industrial requirements, can be fabricated from a variety of materials.Read More →
