Industrial Disc Spring Product Solution: Technical Parameters and Selection Comparison of Three Types of Professional Disc Spring
As a professional manufacturer of elastic components, Jiangsu Sunzo Industry provides a comprehensive range of disc spring products. Our disc springs are designed and manufactured in strict compliance with the GB/T 1972 national standard, while also meeting international standards such as DIN 2093. Below are our three core product categories, each optimized for specific industrial applications.
product orientation ：
The standard series disc springs are our most widely used product line, suitable for most general industrial applications, achieving a good balance between performance reliability and economy.
Technical features:
Material system: High-quality spring steel (60Si2MnA or 50CrVA) is used to ensure stable material properties.
Precision level: Offers two precision levels (Level I and Level II) to meet various assembly requirements.
Surface treatment: Standard phosphating treatment with anti-rust oil application for basic protection
Specifications: Outer diameter ranges from 8mm to 400mm, thickness from 0.5mm to 25mm.
Load accuracy: Within the ±10% tolerance range specified by national standards
Typical application:
Buffer and Shock Absorption of General Purpose Machinery
conventional bolt pre-tightening device
Medium-load clutch engagement
Reset element of valve actuator
product orientation ：
