What component helps to keep the rod clean and protects the rod seal?

The rod wiper is designed specifically to ensure the cleanliness of the rod and to protect the rod seal from contamination. As the rod retracts and extends, the wiper removes dirt, debris, and moisture that could interfere with the proper functioning of the seal. This action helps maintain the integrity of the hydraulic system by preventing contaminants from entering the cylinder and damaging the seals, which could lead to leaks or reduced performance.

In hydraulic systems, a clean rod surface is crucial for optimal operation, and the rod wiper plays a vital role in achieving that. It acts as a barrier that safeguards the seals from abrasive particles and fluid that the rod may encounter during operation, thereby enhancing the longevity of both the rod and the seal.
