ShanghaiProduct Description
HRD Polyurethane U-Cup Rod Seal is a high-performance rod sealing solution designed for hydraulic cylinders operating under demanding conditions. Featuring a primary sealing lip and an auxiliary lip, the HRD effectively retains a lubricating oil film between the two lips, reducing friction and minimizing seal wear during operation.
Manufactured from premium polyurethane material, this Polyurethane Rod Seal for Hydraulic applications delivers excellent dynamic and static sealing performance, outstanding wear resistance, and reliable low-pressure sealing capability. Its optimized design helps extend seal service life and ensures stable performance even under pressure fluctuations and shock loads. For telescopic and multi-stage cylinders, larger cross-section sizes are recommended to achieve optimal sealing results.
