Rod Seals
Rod Seals
A rod seal is a type of seal used in hydraulic and pneumatic cylinders to prevent fluid from leaking out of the cylinder and to keep contaminants from entering the system. It is located at the entry point where the piston rod exits the cylinder, ensuring that the pressure within the cylinder is maintained and that the fluid stays within the cylinder.
Key Functions and Characteristics
Rod seals are crucial components in ensuring the efficiency and longevity of hydraulic and pneumatic systems, commonly found in machinery, automotive applications, industrial equipment, and more.
Leak Prevention
Rod seals prevent hydraulic fluid or air from leaking out of the cylinder as the piston rod moves in and out.
Contaminant Exclusion
They help keep dirt, dust, and other contaminants from entering the cylinder, which can otherwise lead to wear and damage.
Pressure Retention
Rod seals help maintain the pressure necessary for the hydraulic or pneumatic system to function effectively.
Durability
They are typically made from materials such as polyurethane, rubber, or PTFE (polytetrafluoroethylene) to ensure durability and resistance to wear and tear.
Designs
There are various designs of rod seals, including single-acting, double-acting, and compact designs, tailored to different applications and operating conditions.
