The Enduraflex INT provides a larger interference face provides several key advantages, including improved sealing efficiency, enhanced durability, and better wear resistance. The increased contact area between the seal and the rod surface ensures a tighter and more effective seal, reducing fluid leakage and extending the lifespan of the seal by distributing wear and stress over a larger area. This design also improves stability and resistance to extrusion, particularly under high-pressure conditions, making it well-suited for demanding applications.
However, it’s important to note that a larger interference can lead to increased friction, which may affect the efficiency and smooth operation of the system. This consideration is particularly critical in applications where minimal friction is essential for functionality, such as in precision hydraulic systems and in equipment where energy efficiency is a priority. Despite this, in environments that require robust sealing capabilities to handle high pressures, dynamic loads, or the presence of contaminants, the benefits of more interference—such as enhanced sealing performance and durability—often outweigh the drawback of increased friction.
