Belleville washers—also known as conical washers or disc springs—are designed to help fasten heavy loads and withstand vibrations or thermal expansion without a loss of torque. As a type of heavy-duty spring washer, their convex shape maintains optimal axial loading (i.e., applying force to a structure along its axis) to prevent hardware creep challenges.
Below, we’ll provide a breakdown of what you need to know about Belleville washers.
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.
