Let's check common profile as below:
Piston seals
Piston seals, as the name suggests, are installed on the piston head of hydraulic or pneumatic cylinders. Their primary function is to prevent fluid from passing across the piston and ensure that pressure is maintained within the cylinder. These seals play a crucial role in enabling the controlled movement of the piston, translating fluid power into mechanical work efficiently.
Rod Seals
Rod seals, including U-cups and Polypaks@, are critical
components in hydraulic and pneumatic systems. They are installed on the reciprocating rod or shaft of a cylinder to prevent fluid leakage from the system. U-cups, with their distinctive U-shaped profile, offer efficient sealing for various applications, while
Polypaks@ provide excellent sealing performance with an O-ring expander. These seals ensure that hydraulic or pneumatic pressure is maintained within the cylinder, allowing for the controlled movement of the rod.
Wipers
Wiper seals, also called scraper seals, are essential for maintaining the cleanliness of hydraulic and pneumatic systems. They are typically installed on the outer side of hydraulic or pneumatic
cylinders to prevent contaminants like dust, dirt, and moisture from entering the system. Wipers help extend the lifespan of other
sealing elements, such as rod seals and piston seals, by minimizing wear and preventing damage to the cylinder's internal components.
Backup Rings
Backup rings, or anti-extrusion rings, support O-rings in hydraulic and pneumatic applications, preventing their extrusion or damage under high pressure. In hydraulics, they enhance O-ring performance and longevity, maintaining sealing integrity.Similarly, in pneumatics, backup rings provide reinforcement to O-rings, especially in higher pressure systems, ensuring reliable sealing solutions. These rings work in tandem with 0-rings to contain fluids and maintain pressure while preventing leakage. Proper material and size selection are crucial for their effectiveness.
Guide Rings
Guide rings, also known as wear rings or guide bands, are used to reduce friction and minimize wear between moving components in hydraulic and pneumatic systems. They are typically installed on the inside of hydraulic cylinders to guide and support the piston or rod. Wear rings provide a smooth and stable surface for these components to move against, increasing system efficiency and longevity by reducing frictional losses and wear.
Rotary Seals
Rotary seals, also known as radial shaft seals or lip seals, are
essential components in hydraulic and pneumatic systems. Installed on rotating shafts or axles, their primary role is to create a fluid or gas-tight barrier while accommodating rotational movement. These seals prevent the escape of fluids and contaminants,
ensuring efficient and reliable operation of machinery. With various designs available, including single-lip, double-lip, or multiple-lip configurations, rotary seals are versatile and find application in diverse industries like automotive, manufacturing, aerospace, and marine. They contribute to reduced friction, longer equipment lifespan, and the integrity of fluid or gas containment in rotating systems.
