High Torque Disc Spring Designed for Extreme Torque and Durability
Engineered for Extreme Conditions

Designed specifically for environments where rotational forces exceed 10,000 Nm and operational temperatures range from -50°C to 250°C, this disc spring delivers unwavering performance under relentless stress.

Premium Material & Manufacturing

Forged from aerospace-grade chromium-vanadium alloy (ASTM A231 standard) and subjected to a proprietary dual-stage heat treatment process:

  • Vacuum quenching at 860°C followed by tempering at 450°C
  • Tensile strength of 2000 MPa
  • Rockwell hardness of HRC 52-54
  • Exceptional resistance to plastic deformation and fatigue
Superior Performance & Durability

Maintains 95% of initial torque capacity even after 100,000+ cycles in accelerated life testing—significantly outperforming conventional springs that degrade after just 10,000 load cycles.

Precision Engineering

Features a precision-engineered dished profile with 15° conical angle and optimized 1:8 thickness-to-outer-diameter ratio for uniform torque distribution across mating surfaces.

  • Reduces localized stress by up to 35% compared to flat washers
  • Edge-beveled design minimizes stress risers
  • Corrosion-resistant zinc-nickel coating (1000+ hours salt spray resistance per ASTM B117)
Critical Applications
Aerospace engine turbine mounts (secure at 12,000 RPM)
Formula 1 gearbox assemblies
Heavy-duty industrial presses
Offshore drilling rigs
Electric vehicle powertrains
Wind turbine nacelles
Mining equipment
Marine and chemical processing environments
Quality Assurance

Backed by finite element analysis (FEA) validation and ISO 16232-3 compliance, ensuring consistent performance where failure is not an option.
