4717170150 RING WEARFor HITACHI ZW550 QSK19

The ring wear is a component used in hydraulic cylinders, pumps, and rotating machinery to guide moving parts and reduce metal-to-metal contact. Its primary function is to absorb lateral loads, maintain alignment between components such as pistons and cylinder bores, and prevent direct wear on critical metal surfaces. By doing so, it enhances equipment longevity and ensures smooth, efficient operation. Commonly made from non-metallic, wear-resistant materials like PTFE, nylon, or composite plastics, wear rings are essential for minimizing friction, improving performance, and reducing maintenance in high-stress mechanical systems.
