Arm Seal Kit Description
The JSY22.5-DG arm cylinder seal kit is specifically engineered for Sany SY225 excavators, designed for arm (stick) hydraulic cylinders with a 100mm rod diameter. It is widely used in hydraulic maintenance and overhaul processes where sealing performance is critical to ensure stable machine operation.
All components, including piston seals, rod seals, wiper seals, and O-rings, are manufactured under strict quality control standards. Advanced materials such as polyurethane and NBR are used to provide excellent resistance to wear, pressure, and hydraulic oil. As a result, stable sealing performance is maintained even in demanding environments such as construction, mining, and heavy-duty earthmoving operations.
This arm cylinder repair kit is widely selected by distributors, maintenance workshops, and equipment owners who require consistent quality and stable supply. With YNF Machinery, bulk supply is supported, helping B2B customers reduce downtime, maintain inventory efficiency, and improve overall profitability in local markets.
