The wiper ring, also known as a rod scraper, acts as a barrier at the outer end of a hydraulic or pneumatic cylinder. Its primary function is to clear dust, dirt, moisture, and debris from the surface of the cylinder rod as it retracts into the housing. By preventing these external particles from entering the cylinder assembly, the component helps maintain the integrity of the internal seals and the cylinder bore.
This specific part, identified by number 0782 384 07, is compatible with the Terex HC230 crane. It is installed at the gland end of the cylinder to ensure the rod remains clean during operation.
Wiper rings serve a critical role in hydraulic systems by preventing the contamination of hydraulic fluid. When a rod extends and retracts, it often carries environmental debris; the wiper ring scrapes this material away before it can bypass the primary seal. This process reduces the risk of scoring on the rod surface and prevents internal seal damage, which can lead to pressure loss or fluid leakage within the hydraulic circuit.
