The hydraulic cylinder rod seal, also abbreviated as hydraulic rod seal or hydraulic cylinder seal, is often installed in the dust seal inside the hydraulic cylinder end cap. Acting as one of the primary pressure bearing components, the hydraulic rod seal prevents the hydraulic oil from leaking, and this means the rod seals hold compression force in the cylinder by preventing fluid from leaking out. The leakage happening through the hydraulic rod seal will eventually affect the equipment performance or even lead to environmental issues.

 

The robust seal profile enables it to use in the hardest operating conditions, such as high-pressure applications. The hydraulic field is hugely demanding for the seals. The hydraulic cylinder seals not only prevent the fluid leakage from the cylinder, but they are required to withstand high pressures, extreme temperatures, and transverse forces within the cylinders. In such applications, the function of the hydraulic rod seal goes far beyond preventing fluid leakage. Usually, the working medium of the seals is water, air, mineral oil-based hydraulic fluids, barely flammable hydraulic fluids, or other kinds of chemical liquids. Of course, there are many different cross-section forms and materials for the hydraulic rod seal. The cross-section and materials should be chosen mainly based on what kind of working conditions is. Generally speaking, selecting the right seal is vital for guaranteeing the best performance for hydraulic cylinder applications. Commonly used in the hydraulic system, the hydraulic cylinder seal has stable pressure holding capability in the static condition, excellent pressure-bearing capability in operation, good sealing effect, small friction coefficient, as well as remarkable extrusion resistance. Usually, the hydraulic cylinder seals are made of Polyurethane (PU), fluoro rubber (FKM) or nitrile -butadiene rubber (NBR) materials.

 

 

Here, the Polyurethane hydraulic seal/PU rod seal will emphatically introduce. Polyurethane material, regarded as the best insulation materials in the world, can ensure maximum durability and performance with minimum maintenance of the seal. The hydraulic cylinder seal DSH Seals offers is fabricated from high-grade materials in compliance with the standards. When it comes to sealing the hydraulic cylinder, the PU rod seals in DSH Seals are the best choice due to the following characteristics.

 

-High-pressure resistance. The PU materials itself feature excellent physical properties and often used in medium or high-pressure conditions.

-Extraordinary efficiency. The PU rod seal is specially engineered for the hydraulic system with an excellent sealing effect.

-Excellent wear resistance.

-Better compression performance. It has a strong ability to rebound to its original shape after compression without sacrificing tensile strength and the hardness levels of the hydraulic rod seal.

-Wide working temperature range. The hydraulic rod seal can work stably under extreme temperatures without seal degradation.

-Excellent capability in compensating the deflection of the piston rod.

-Easy installation and replacement.
