SUNZO Disc Spring vs. Compression Spring: Engineering Comparison of Design, Performance & Application Suitability
Overview

SUNZO disc springs and compression springs exhibit fundamental differences in design, performance characteristics, and application suitability. Understanding these distinctions enables optimal spring selection for specific engineering requirements.

Design & Geometry Comparison

Disc Springs: Conical profile with optimized dish height-to-thickness ratios (0.4-1.2) and typical cone angles of 12°-18°. Achieve 30-70% axial space savings compared to compression springs of equivalent load capacity.

Compression Springs: Helical coils with variable pitch (0.5-2.0× wire diameter) and spring indices (5-15). Designed for longer stroke applications.

Performance Parameters
Parameter Disc Springs Compression Springs
Stiffness Range 5-50 N/mm (2-3× higher stiffness-to-volume ratio) 1-20 N/mm
Load Capacity 0.5-50 kN (via stacking) 100 N-10 kN (single spring)
Deformation Characteristics Non-linear load-deflection curves (adjustable via parallel/series stacking) Linear behavior under elastic load
Materials & Applications
  • Disc Springs: High-strength alloys (Inconel718, 50CrVA) for extreme environments. Ideal for hydraulic valve preload (350+ bar systems), aerospace landing gear, and precision CNC tooling.
  • Compression Springs: Carbon steel or stainless steel (琴钢丝, SUS304). Suited for automotive suspension (10-50 mm stroke), household appliances, and general industrial shock absorption.
Engineering Selection Criteria

Choose Disc Springs for: Space-constrained applications, high-stiffness requirements, variable-load scenarios, and axial preload applications where precision is critical.

Choose Compression Springs for: Longer stroke requirements (10-100 mm), cost-sensitive general applications, and situations requiring linear force-deflection characteristics.

Quality Standards

Disc springs comply with ISO 16148/DIN 2092 standards, while compression springs adhere to ISO 10243, ensuring interchangeability and performance consistency across applications.
