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.

If you don’t see what you are looking for in our standard offering (including size, quantity, stacks, etc.), please feel free to Request a Quote or contact SPIROL directly for complimentary Application Engineering assistance!

Note: All pricing is based on small box quantities. Please contact SPIROL directly for high volume quotes!

Disc Springs are available as single Discs or pre-stacked in custom configurations.
