Manufacturer Factory Price 4K-7463 CAT Seal for Drill Machines

This composite seal (Model 4K-7463) is a high-performance sealing component engineered for mining drilling rigs and heavy construction machinery hydraulic rotary systems. Featuring an annular structure with a metal skeleton and NBR rubber sealing lip, it is manufactured via integral molding vulcanization to ensure strong bonding between rubber and metal. The galvanized metal skeleton provides excellent corrosion resistance, while the precision-trimmed NBR lip delivers a tight seal against fluid leakage in high-pressure, high-vibration mining environments. With optional PTFE coating on the sealing lip for low-friction operation, it is a critical spare part for maintaining the reliability of hydraulic systems in harsh working conditions.
