Hydraulic cylinder systems are sealed using a complex configuration of high performance seals, and we offer a wide range of seals for applications within these cylinder systems as per requirements and specifications to suit any machine.
Hydraulic Seals in hydraulic applications plays a important function in hydraulic cylinder which convert fluid power into mechanical powers , are also known as JACKS or RAMS, they are used at high pressure and produce large forces and precise movement.
In pneumatic application hydraulic seals are used preventing leakage from gas/liquid as it is an expansive substance , its is dangerous to use at high pressure, as they limit to about 10 bar pressure, because gas / liquid is compressible substance , the motion of pneumatic cylinder is hard to control precisely .The basic theory for hydraulic & pneumatic cylinder is otherwise the same.
Hydraulic Seals prevent leakage of fluid from within the cylinder to the outside,hydraulic seals can withstand extreme temperatures, pressure situations and environmental conditions to help provide exceptional performance in handling hydraulic fluid pressures.
Hydraulic Seals are used where there is leakage, resistance to wear and gap extrusion, resistance to process media, resistance to high and low temperatures ,low friction, compact form and simple installation are demanded for the requirements of industry for a functional sealing solution.Hydraulic Seals are used usually for the rod, ram, gland or piston, seals are of numerous profiles and sizes depending on their application as required for performance in hydraulic equipments for dynamic reciprocating, oscillating or very slow rotational motion and which are based on the design, function and service life of hydraulic and pneumatic cylinders and systems.
Piston Seals: prevent leakage from one side to other, seals between the reciprocating piston and cylinder bore.
Rod/Gland Seals: prevent leakage from the rod end ,seal around the reciprocating rod or ram.
Wipers/Scrapers: stop external contaminants from being drawn inside with the rod ,such as dust, dirt or water.
Wear Rings: provided support to the piston or ram under lateral loads.
O Rings: prevent leakage from joints between the barrel & end joints also used as static seal.
