Each product has undergone rigorous load testing and dimensional inspection.
The DIN2093 standard specifies the dimensions, materials, heat treatment, and load characteristics of disc springs, ensuring interchangeability among products from different manufacturers. The DIN2093 disc springs produced by Sunzo Technology fully comply with the standard requirements, with all dimensions—including outer diameter, inner diameter, thickness, and free height—controlled within the standard tolerance limits.
The standard specifies the load values of disc springs at 25%,50%, and 75% compression, providing users with precise selection criteria. Sunzo Technology conducts random load tests on each batch of products prior to shipment to ensure that the measured values deviate within the permissible range of the standard values.
The DIN2093 disc spring can be manufactured from various materials depending on operational requirements.
51CrV4/50CrVA: High-temperature resistant and excellent fatigue resistance, suitable for dynamic load applications
60Si2Mn: High strength, good cost performance, suitable for conventional working conditions
65Mn: Good Machinability, Suitable for Thin Disc Spring

In the hydraulic disc spring actuator developed by Sunzo Technology for China National Nuclear Corporation (CNNC), the disc spring serves as the core energy storage component. A motor-driven oil pump generates hydraulic pressure to compress the spring and store energy. When activation is required, the hydraulic system releases pressure, instantly releasing the stored energy to enable rapid circuit breaker operation. This application imposes extremely high demands on the fatigue life and load stability of the disc spring.
In industrial valves and piping systems, DIN2093 disc springs provide continuous sealing preload to compensate for dimensional changes caused by temperature variations and pressure fluctuations. Stainless steel disc springs are widely used in chemical pipelines, high-pressure switches, and similar equipment to resist medium corrosion.
In wind turbine pitch control systems and yaw brake mechanisms, disc spring assemblies provide stable braking force and cushioning protection. Their high rigidity and compact axial dimensions make them ideal for large-scale wind power equipment.
In the clamping mechanism and hydraulic locking device of CNC machine tools, the disc spring provides strong clamping force through overlapping combination, ensuring machining accuracy and operational safety. Its force designability and flexible combination offer reliable elastic solutions for precision equipment.
In the steering system and axle brake device, DIN2093 disc spring is a key safety component that provides stable and reliable braking force to ensure vehicle safety.
Select the appropriate specification based on installation dimensions (inner diameter, outer diameter, axial height). The recommended clearance between the guide and disc spring is as follows:
Outer diameter ≤16mm: clearance 0.2mm
Outer diameter 1620mm: clearance 0.3mm
Outer diameter 2026mm: clearance 0.4mm
Outer diameter 2631.5mm: clearance 0.5mm
Outer diameter 31.550mm: clearance 0.6mm
Outer diameter 5080mm: clearance 0.8mm
Outer diameter 80140mm: clearance 1.0mm
Outer diameter 140250mm: clearance 1.6mm
Outer diameter>250mm: clearance 2.0mm
Select the appropriate specification from the parameter table based on the required working load and compression volume of the equipment. The standard provides load values for 25%,50%, and 75% compression volumes, which can be used to calculate force values at other compression points.
