Belleville washers provide a compact, reliable solution to differential thermal expansion. By maintaining bolt tension as materials expand and contract, they keep connections stable in high-temperature environments such as turbines, automotive systems, and petrochemical equipment. Learn how these precision-engineered disc springs protect critical assemblies and improve joint longevity.
Bolt fatigue is a common cause of fastener failure in high-stress industrial settings. Understand what causes bolt fatigue to avoid costly downtime, safety issues, and equipment damage. American Belleville helps engineers solve this with Belleville washers, which are proven to reduce fatigue and enhance reliability.
Our material selection will accommodate working temperatures from -400 deg. F to 1100 deg. F, various corrosive environments and magnetism requirements.
Our Flange Washer line adds deflection to bolted joints, in order to dramatically reduce the effects of large fluctuations in temperature within the application.
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.
