American Belleville Disc Springs are manufactured to exacting standards, where predictability, repeatability and long fatigue life are paramount.

Governed by the specifications outlined in the European DIN EN 16984/16983 (formerly DIN 2092/2093), they are engineered and manufactured to perform as needed in the most arduous dynamically loaded spring applications, where high load relative to available space is required.

Limitless stacking configurations help the end user achieve load curves that are either regressive, linear or progressive.

Our load/deflection calculations utilize a balanced combination of time-tested theoretical formulas and field-verified results.

 

American Belleville offers as-delivered options that include bulk packaging and pre-assembled stacks, per design specifications.

Available materials include:

  • High-carbon Steel Alloy AISI 1074 (ASTM A684)
  • AISI 6150 (50CrV4/51CrV4) Chrome Vanadium Steel (ASTM A506)
  • 301 Stainless Steel (ASTM A666)
  • 17/7PH Stainless Steel (ASTM A693)
  • Inconel 718 (ASTM B670 / AMS 5596)
  • 510 Phosphor Bronze (ASTM B103)

Our material selection will accommodate working temperatures from -400 deg. F to 1100 deg. F, various corrosive environments and magnetism requirements.

Additionally, several plating/finish options can achieve desired aesthetics and ensure proper resistance to environmental elements that would otherwise affect performance and longevity.

We will work closely with you to specify or design, and then manufacture the proper part for your application. Contact us online or call 440-721-8350.
