Belleville Washers

View Products

American Belleville washers hold your bolted joint tight in the face of the most extreme cases of differential thermal expansion / contraction, bolt creep & vibration that threaten the integrity of the joint. We specialize in high-temperature applications and the most corrosive environments where first-rate quality is not just important, but necessary.

Offering a design that allows for very high load capacity, relative to deflection and available space within the application, American Belleville washers can be specified using limitless dimensional configurations and load/deflection ratings. Whether the washer needs to fit tightly under the head of the bolt, or provide a wide bearing surface across the mating flange, our products offer long fatigue life, predictable & consistent performance and the reliability that may be missing in your current solution.

 

American Belleville washers may be stacked in order to achieve added load or greater deflection, as well.

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.
