Disc Springs

Disc Springs are conically-shaped, washer-type components designed to be axially loaded. What makes Disc Springs unique is that based on the standardized calculations of DIN EN 16984 (formerly DIN 2092), the deflection for a given load is predictable and the minimum life cycle can be determined. Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singly or in multiples stacked parallel, in series or in a combination thereof.

The SPIROL range includes all Disc Springs specified in DIN EN 16983 (formerly DIN 2093), Groups 1 and 2, 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 based on the standardized calculations of DIN EN 16984 (formerly DIN 2092). Standard materials include high carbon steel, alloy steel and stainless steel.

SPIROL also supplies pre-stacked Disc Springs in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

standard disc springs
Standard Disc Springs (per DIN EN 16983 (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.
stainless steel disc springs
Stainless Steel Disc Springs
SPIROL offers a line of austenitic stainless steel Disc Springs in diameters ranging from Ø8mm to Ø71mm. Austenitic stainless steel is typically used for static and low cycle applications that require a heightened level of corrosion resistance. It withstands fresh water and atmospheric marine conditions very well, and is suitable for many other industrial conditions including acidic environments. This material will continue to work harden with use so cycle life is limited, but creep resistance is good.
pre-stacked disc springs
Pre-Stacked Disc Springs
SPIROL offers Disc Springs pre-stacked in custom configurations (greased or ungreased) packaged in shrink wrap with a perforated tab for ease of insertion into the assembly. The pre-stacked Disc Springs are delivered intact which saves time, mistake-proofs the assembly process, and eliminates the mess associated with greasing the stack. SPIROL Engineering will assist in determining the optimum Disc configuration to meet your specific application requirements.
