What is the role of a rod wiper in hydraulic systems?

The role of a rod wiper in hydraulic systems is primarily to clean the rod and protect the seal. As the rod moves in and out of the cylinder, it can accumulate dirt, debris, and other contaminants. The wiper is designed to scrape away these contaminants as the rod retracts, thereby preventing them from entering the hydraulic system and causing potential damage to the seals and other components. This helps to maintain the integrity of the hydraulic system and ensures smooth operation.

By keeping the rod clean, the wiper also contributes to the longevity of both the seals and the hydraulic fluid by minimizing the risk of leaks and contamination. This is essential for maintaining optimal performance and reliability in hydraulic applications.
