Boom Seal Kit Description
The JSY22.5-BD boom cylinder seal kit is engineered for Sany SY225 excavators, especially designed for boom cylinders with an 85mm rod diameter. It is widely applied in hydraulic repair and maintenance operations where sealing integrity directly affects machine performance and operational safety.
All sealing components, including piston seals, rod seals, wiper seals, and O-rings, are manufactured under strict quality control systems. Advanced materials such as polyurethane and NBR are selected to ensure superior resistance to wear, heat, and hydraulic oil. As a result, consistent sealing performance is maintained even under high-load working environments such as construction and mining.
This boom cylinder repair kit is commonly chosen by distributors, maintenance workshops, and equipment owners who require stable quality and reliable supply. With YNF Machinery, B2B buyers can benefit from bulk supply capability, helping reduce downtime, stabilize inventory, and increase profit margins in local markets.
