Hydraulic Seals

Hydraulic seals & Pneumatic seals are designed as per the cylinder working pressure, cylinder speed, operating temperature, working medium and application

Hydraulic Seals

Hydraulic seals are generally relatively soft, non-metallic rings captured in groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion.

Hydraulic seals can be made from a variety of materials such as polyurethane, rubber or PTFE. The type of material is determined by the specific operating conditions or limits due to fluid type, pressure, fluid chemical compatibility or temperature.

A static hydraulic seal is located in a groove and sees no movement – only sealing within its confined space, acting like gasket.

A type of dynamic hydraulic seal called a rod seal is exposed to movement on its inner diameter along the shaft or rod of a hydraulic cylinder. A type of dynamic hydraulic seal called a piston seal is exposed to movement on its outer diameter along the tube or bore of a hydraulic cylinder.

Piston Seals

Hydraulic piston seals are components used in hydraulic systems to prevent fluid leakage and maintain proper pressure within the system. They are typically installed in the cylinder bore and provide a dynamic sealing solution between the reciprocating piston and the cylinder wall.

Rod Seals

Hydraulic rod seals are critical components used in hydraulic systems to prevent leakage and maintain the integrity of the system. They are installed around the rod or shaft of a hydraulic cylinder and act as a barrier between the internal hydraulic fluid and the external environment.

Wiper Seals

Hydraulic scraper seals, also known as wipers or scraper rings, are components used in hydraulic systems to protect the hydraulic cylinders from external contaminants such as dirt, dust, moisture, and debris. They are installed in the hydraulic cylinder to prevent these contaminants from entering the system and causing damage to the internal components.

Wear Rings

Hydraulic guide rings, also known as wear rings or guide strips, are components used in hydraulic systems to provide axial or radial guidance to the moving components within the system. They are typically installed in cylinders, piston heads, or other moving parts to minimize friction, control motion, and improve overall system performance.
