Introduction to Rod Seals
Rod seals are crucial components in hydraulic and pneumatic systems. They are designed to prevent the leakage of fluid (such as hydraulic oil) from the cylinder around the piston rod. This not only ensures the efficient operation of the system but also helps in maintaining the cleanliness of the working environment. Rod seals are typically made from a variety of materials including rubber, polyurethane, and PTFE, each with its own set of properties suitable for different applications. They need to withstand high pressures, varying temperatures, and resist wear and tear to ensure long - term and reliable performance.
