Product Description
HNBR Rubber Block | Molded Rubber Parts | High-Temp Oil-Resistant Vibration Isolator

Product Description

This composite oil seal is a high-precision sealing component engineered for critical shaft sealing applications in automotive systems. It features a rigid metal reinforcement shell that provides structural stability and precise installation alignment, paired with a high-performance NBR/FKM rubber sealing core that delivers exceptional oil resistance and dynamic sealing performance. The step-type structural design ensures a tight fit in housing bores, while the inner sealing lip conforms to shaft surfaces to prevent leakage of lubricating oil and intrusion of dust, moisture, and contaminants. Engineered to withstand temperatures from -40°C to 120°C (NBR) or -20°C to 200°C (FKM), it resists petroleum-based fluids, hydraulic oils, and ozone aging, making it ideal for automotive engine crankshafts, transmission output shafts, and industrial mechanical rotating shafts where reliable sealing and long service life are essential.




TECHNICAL PARAMETERS


Category Details
Product Name  Automotive Composite Oil Seal
Part Number 283318585
Material HNBR (Hydrogenated Nitrile Butadiene Rubber), black
Color Black
Core Functions Shaft sealing, oil leakage prevention, dust & moisture protection, vibration damping
Design Feature Step-type metal shell with integrated inner sealing lip; precision-molded for automotive assembly
Application Automotive engines, transmissions, axle systems, industrial mechanical shafts

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.
