Advantages
-
Dual-Structure Synergy: Metal shell offers rigid structural support and installation precision, while rubber sealing core provides elastic sealing and wear resistance—combining strength and flexibility for optimal performance.
Superior Sealing Performance: Integrated inner lip creates a dynamic seal against rotating shafts, effectively preventing oil leakage and external contamination in both static and dynamic operating conditions.
Easy & Accurate Installation: Precision-molded metal shell ensures error-free alignment during assembly, reducing installation time and improving fitting consistency.
Wide Environmental Tolerance: Rubber core resists high/low temperatures, oil, and aging, adapting to harsh automotive engine bays and industrial working environments without performance degradation.
Durable Service Life: The composite structure resists wear, compression set, and mechanical damage, extending service life by 2–3 times compared to single-material seals in high-load applications.
Applications:
- Seals automotive engine crankshafts and camshafts, preventing engine oil leakage and maintaining lubrication system integrity.
- Retains lubricating oil in automotive transmissions and axle systems, protecting internal gears and bearings from wear and contamination.
- Provides dust and moisture protection for industrial mechanical rotating shafts, extending the service life of pumps, motors, and gearboxes.
- Dampens vibration between the shaft and housing in dynamic systems, reducing operational noise and mechanical wear.
- Ensures leak-proof performance in hydraulic system drive shafts, maintaining pressure stability and preventing fluid loss in industrial machinery.
