Wiper ring for Terex HC230

The wiper ring is a sealing component installed on hydraulic cylinders to prevent external contaminants such as dust, dirt, moisture, and debris from entering the internal sealing system. By scraping the piston rod as it retracts, this component ensures that foreign particles do not reach the primary seals or the hydraulic fluid circuit. This protection helps maintain the integrity of the cylinder assembly and prevents damage to internal surfaces during operation.

This specific component is compatible with the Terex HC230 crane. It is designed to fit the cylinder specifications for this model, ensuring proper clearance and sealing performance on the piston rod. Proper maintenance of the wiper ring is necessary to support the function of cylinders used in boom movements, outriggers, and other hydraulic actuators found on this machinery.

Wiper rings serve as the first line of defense in hydraulic systems. They are typically installed at the rod end of a cylinder to exclude contaminants while allowing the rod to move smoothly through its stroke. By keeping the rod surface clean, they prevent abrasive particles from being drawn into the cylinder, which otherwise leads to seal failure and leakage.
