Rod seals are largely used in hydraulic cylinders for the purpose of fluid sealing. When it comes to fluid
power equipment, these are one of the most important seals. They help to prevent leakage in the
pressurized hydraulic fluid that is found inside of the cylinder, and therefore, saves the equipment from
reduced performance, safety or environmental issues and system failure.
Rod Seals Help to Generate Pressure
Rod seals are dynamic seals that are placed inside the cylinder head, which is also known as gland. They
are typically compressed against the rod of the cylinder. It contains the fluid and enables the generation
of pressure. There are also rod seals that are specifically designed and engineered for difficult or
demanding applications that are subject to arduous and extreme operating conditions. These designs
are found commonly in medium and heavy-duty construction, mining, excavating and off-highway
equipment. Rod seals that are designed for high-speed operating conditions or low friction can be found
in engine bearings and pumps.
Rod Seals Suit a Variety of Conditions and Applications
Rod seals are found in a wide variety of high-performance materials that cater to a broad range of
temperature, fluid requirements and operating conditions. The material influences the design of the rod
seal and it is critical to select the right profile and material so that the rod seal can be aligned with the
requirement of the application. In order to make sure that the rod seal is able to perform its sealing duty
to the optimal, they can be paired with an appropriate scraper or wiper in order to prevent
contamination from entering inside the system. This helps to create a second layer of protection and it is
important as contamination is one of the most common reasons for the failure of hydraulic system.
