Description
SUNZO 51CrV4 Disc Spring High-Elasticity Solutions for Precision Machinery Applications
Product Overview

SUNZO 51CrV4 Disc Spring is engineered specifically for precision machinery applications where consistent performance and dimensional stability are critical. Manufactured from high-carbon spring steel renowned for exceptional elastic properties, these disc springs deliver reliable performance in demanding precision equipment environments.

Material Properties
Chemical Composition 0.62-0.70% carbon, 0.90-1.20% manganese, with trace elements of silicon and phosphorus
Tensile Strength 1,000-1,200 MPa
Yield Strength 800-950 MPa
Elastic Recovery <0.1% permanent deformation after 10⁵ cycles
Performance Characteristics
  • Load Range: 0.5-15 kN for small to medium load applications
  • Superior shock absorption with damping coefficient of 0.25-0.35
  • Stiffness range: 8-45 N/mm depending on thickness (0.5-5mm) and outer diameter (10-150mm)
  • Conical geometry enables precise load-deflection control
  • Ideal for compact mechanical assemblies
Surface Treatments
  • Phosphating (per ISO 10276): Creates corrosion-resistant phosphate film (5-15μm thickness) suitable for dry indoor conditions
  • Blackening (per MIL-DTL-13924): Forms uniform oxide layer that improves wear resistance and aesthetic finish
  • Optional Oil-Impregnated Treatments: Reduces friction coefficients by 30% compared to untreated surfaces
Applications & Quality Assurance

Available in both standard DIN 2092 sizes and custom configurations with tolerances as tight as ±0.02mm for critical dimensions. Rigorous quality testing includes load-deflection curve validation (±3% tolerance) and hardness testing (42-48 HRC).

Ideal applications include CNC machine tool spindles, coordinate measuring machines (CMMs), optical inspection equipment, servo motor brakes, precision press tools, and semiconductor manufacturing equipment.
