Sealing solutions engineered for enhanced cylinder efficiency

Friction

Friction losses occur in fluid power components on industrial equipment due to the dynamic nature of their operation. For example, as hydraulic cylinders extend and retract on a bulldozer, friction can lead to greater energy requirements for operation potentially causing overheating.

Reducing friction in the components that interact with the machinery contributes to reducing energy consumption and improves the overall sustainability of the equipment. This has led companies to explore new types of lubrication, materials, and product geometries that offer less frictional drag. Hallite for example highlights that it is focused on reducing friction in hydraulic cylinder sealing systems by test methods to assess friction durability and understand the impact on longer term sealing properties. This has been the catalyst for the development of new seal profiles and materials, such as the 683 low friction rod seal, an asymmetric single-lipped rod seal designed with precision-trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. Its design provides low friction to help lower fuel consumption, reduce emissions and optimise performance.

Minimising friction through proper design, material selection, and maintenance can deliver optimal performance and longevity of hydraulic sealing components.

Hydraulic fluid quality

Using substandard fluid can affect lubrication and cooling, leading to premature wear and inefficiencies. Hydraulic fluid types are broadly defined by ISO6743-4 into three categories: biodegradable, mineral oil, and fire resistant. Therefore, it is important to properly pair sealing materials with hydraulic fluids. The right fluid and material combinations can ensure the longevity of hydraulic sealing systems to prevent downtime and minimize leaks caused by potential incompatibilities.

Using improper viscosity fluids can starve the seal of essential lubrication, resulting in excessive wear. On the other hand, the right viscosity ensures optimal lubrication, reducing friction between seals and their mating surfaces, which minimise wear and tear. This balance prevents overheating, allowing seals to maintain their shape and integrity over time, which also reduces the likelihood of leaks.

Finally, fluids with the correct viscosity facilitate efficient fluid flow, enhancing the overall responsiveness of the hydraulic system. By maintaining consistent pressure and reducing cavitation risks, proper viscosity fluids help protect seals from damage, ensuring reliable operation and extending the lifespan of hydraulic components.

When it comes to hydraulic sealing solutions that promote cylinder efficiency, there are several options depending on the application and operating environment. Solutions that address the most common challenges must consider design and material parameters that contribute to the greatest potential for successful performance.
