Oil & Gas Seal Spring

Precision-Engineered by Handa Seal | Trusted by OEMs Worldwide

Handa Seal’s Oil Seal Springs are purpose-designed metallic springs used to energize oil seals in demanding environments. By maintaining optimal lip pressure against shafts or housings, they prevent oil leakage—even at high speeds, under heavy loads, and across wide temperature ranges. Ideal for industrial machinery, automotive systems, marine applications, and power generation equipment, these springs ensure reliability in mission-critical applications.

Why Oil Seal Springs Matter

Oil Seal Spring energizers maintain consistent radial pressure across the seal lip—even under high RPMs and thermal fluctuations. This prevents lubricant escape and contaminant ingress better than passive seals alone, extending equipment uptime and protecting valuable components.

Why Choose Handa Seal’s Oil Seal Springs？

    • ✅ Superior Seal Performance
      Delivers consistent radial pressure, combating pressure surges and thermal expansion to maintain tight oil containment.

    • ✅ High-Speed & High-Load Capability
      Designed for rotating shafts and dynamic systems operating at thousands of RPM and high surface velocities.

    • ✅ Robust Material Construction
      Manufactured from premium alloys like 301/304 stainless steel, Inconel®, and Elgiloy® for superior corrosion, wear, and temperature resistance (-50 °C to +250 °C).

    • ✅ Space-Efficient Geometry
      Compact spring designs allow for integration into confined assemblies without sacrificing seal effectiveness.

    • ✅ Customizable for OEM Specifications
      Spring force, dimensions, coatings (e.g., nickel or silver), and tolerances tailored to your system requirements.

🏭 Typical Applications

  • Industrial Gearboxes & Pumps – Ensuring oil retention under heavy loading and repeated shaft motion.

  • Automotive Transmissions & Differentials – Prevents fluid leakage and protects internals in high-speed rotational systems.

  • Marine Shaft Sealing – Handles salt spray, pressure swings, and vibration in marine propulsion systems.

  • Hydraulic Motors & Pumps – Maintains seal integrity in oil-based hydraulic circuits under high pressure.

  • Power Generation Turbines – Used in oil-lubricated bearings and couplings in turbines and generators.
