Automotive Composite Oil Seal | Mechanical Shaft Seal | Precision
Oil Retainer
Product Description
This composite oil seal is a high-precision sealing component
engineered for critical shaft sealing applications in automotive
and industrial systems. It features a rigid metal reinforcement
shell that provides structural stability and precise installation
alignment (via integrated positioning notches), 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.

AdvantagesDual-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: Positioning notches on the metal shell ensure 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.
