DIN EN 16983 Disc Springs
(formerly DIN 2093)
SPIROL offers the full range of DIN EN 16983 (formerly DIN 2093) Group 1 and 2 Disc Springs in Series A, B, and C. In addition to the DIN specified sizes, SPIROL stocks its own standard sizes with outside diameters ranging from Ø8mm to Ø200mm. SPIROL Standard Disc Springs were designed around the standardized calculations of DIN EN 16984 (formerly DIN 2092), and meet all material, dimensional tolerance, and quality specifications as laid out in DIN EN 16983 (formerly DIN 2093) yet offer an expansion in the diameter and thickness combinations that are not included in the DIN standard. Standard materials include carbon steel and alloy steel, both finished with a protective coating of zinc phosphate and oil.
In addition to single Disc Springs, SPIROL also supplies Pre-Stacked Disc Springs stacked in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

Application Success Stories
Disc Spring Stack in Mechanical Clutch in Heavy Duty Right Angle Drill
The lead engineer at a prominent hand and power tool company contacted SPIROL for help determining the best Disc Spring design for a new lightweight, compact, and portable Heavy Duty Right Angle Drill.
- SPIROL Engineering designed two special Disc Springs stacked in series to meet the specific force and deflection requirements.
- Disc Springs offer a higher load capacity in less space as compared to conventional coil springs which enables the designer to make the tool more compact.
- Unlike Belleville Washers that are mostly used in static applications, Disc Springs provide unparalleled predictability, reliability and fatigue life in highly dynamic applications.
- By partnering with SPIROL and incorporating our recommendation, the customer minimized costly development time and confidently launched their new high quality drill to the market.
Disc Springs in Mechanical Braking System
A manufacturer of hydraulic actuated braking systems for Off Highway Equipment approached SPIROL for assistance designing a reliable fail safe system to back up the assembly in the event of a failure. If a hydraulic seal is compromised, or the hydraulic cylinder loses pressure for any reason, the brakes fail. Without an additional fail safe system, this design alone has limited reliability.
- SPIROL Engineering recommended Disc Springs. Due to their predictability, high reliability and unparalleled fatigue life, Disc Springs are preferred over all other types of springs in critical applications such as this fail safe braking mechanism.
- Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series. If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism.
- A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes.
- In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety.
Turret Punch Press Assembly
Traditional turret punch press tool designs utilize coil springs (die springs) to facilitate the stripping mechanism of a die. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process.
- SPIROL Disc Springs are capable of providing a greater, more consistent stripping force than coil springs and require less space when stacked in series.
- To achieve the same spring rate, the coil spring must be seven times larger than the Disc Spring stack.
- Disc Spring Stacks have become an instrumental component in the advancement of turret punch press tooling.
