Rod wiper for Terex BT4792

The rod wiper, part number 226891, acts as a protective seal for the extension cylinder on Terex machinery. It is installed at the entry point of the cylinder rod to prevent dirt, dust, and moisture from entering the hydraulic system during the retraction cycle. By maintaining a clean surface on the rod, this component helps preserve the internal main seals and ensures the purity of the hydraulic fluid.

This specific wiper is engineered for the Terex BT4792 extension cylinder with a diameter of 4.500 inches and a thickness of 0.375 inches. It follows the DX design configuration to ensure a proper fit within the cylinder assembly. Proper maintenance of the rod wiper is necessary to prevent premature wear of internal sealing surfaces and to avoid potential fluid leaks that could compromise the operation of the crane's extension system.

Rod wipers serve as the first line of defense for hydraulic cylinders operating in outdoor environments. By scraping away abrasive particles from the rod surface, they prevent contaminants from being pulled into the cylinder gland, which protects the integrity of the hydraulic circuit and extends the service life of the cylinder components.
