DIN2093 Disc Spring Product Manual: Specification Parameters and Industrial Application Scenarios Analysis
DIN2093 Standard Disc Spring Full Series: Technical Parameters and Industrial Application Analysis
In industrial applications such as mechanical transmission, vibration damping, and pre-tightening mechanisms, the performance of disc springs directly impacts equipment reliability and service life. As a specialized manufacturer of elastic components, Sunzo Technology Co., Ltd. strictly adheres to the DIN2093 international standard, offering a comprehensive range of disc spring products. This article systematically outlines the technical parameters, selection criteria, and typical applications of DIN2093 disc springs, providing valuable insights for industrial design and equipment maintenance.
DIN2093 is the international standard for disc springs, which is compatible with China's GB/T 1972 standard. This standard specifies the size series, load characteristics, material requirements, and testing methods for disc springs, providing a unified technical reference for global engineering designers.
Sunzo's DIN2093 disc springs span the full size spectrum, from miniature (6mm outer diameter) to super-large (600mm outer diameter), meeting diverse industrial requirements. Available in spring steel (50CrV4, 60Si2MnA), stainless steel (SUS302, SUS304, SUS316), and high-temperature alloys (Inconel 718, Inconel X750), these products are engineered for various operational environments.
Each parameter of DIN2093 disc springs corresponds to specific engineering applications:
parameter | symbol | Engineering significance |
external diameter | D | The installation space must match the installation cavity |
bore size | d | The fit dimension shall be determined according to the shaft diameter, with clearance fit required for the guide component. |
thickness | t | The core stiffness parameter is proportional to the cube of the load. |
free height | H₀ | The total height in the unpressurized state determines the initial installation space. |
Flatting height | H₀ h₀ | maximum height at full level |
25%/50%/75% compression load | F | Load values for three key points, used for performance verification |
The following are key technical specifications for the Sunzo DIN2093 standard disc spring (full specifications available upon request from our technical team):
