ShanghaiProduct Description
HRU Composite Mining Rod Seal is a high-performance Polyurethane Rod Seal designed for demanding hydraulic cylinder applications, especially in mining machinery and heavy-duty equipment. The seal consists of a durable polyurethane sealing element combined with an elastomer O-ring energizer, providing enhanced sealing force and long-term reliability.
The integrated O-ring design delivers additional preloading force to maintain effective sealing performance, while also absorbing impact loads during operation. A reinforced backup ring improves resistance to extrusion under high pressure, making this Composite Mining Rod Seal suitable for applications requiring reliable performance under extreme pressure conditions. With stable sealing force under varying temperatures and excellent wear resistance, HRU provides reliable leakage prevention and extended service life in harsh working environments.
