1. Solon® Belleville Springs & Washers are conically shaped
    discs that will deflect (flatten) at a given rate. The spring rate       is usually very high, allowing the spring to produce very large       loads in a very small space.


2. Solon® Belleville Springs & Washers are used in a variety of       applications across many different environments. These        
    springs are used to maintain bolt preload by preventing bolt
    tension loss due to differential thermal expansion, high-    
    temperature bolt yield, packing and gasket relaxation, and
    vibration.


3. One of the most common applications for a Belleville spring is
    a bolted joint. The key to having a sound, bolted joint
    connection is that some minimum preload must be
    maintained. If the preload falls below this minimum, the joint
    will fail. In some applications, joint failure may cause a minor
    nuisance or cosmetic issue. In other applications, failure
    may be catastrophic resulting in significant property loss,
    injury, or death
.


4. Solon® Belleville Springs & Washers can be "stacked" in a
    variety of configurations in order to achieve greater, or more
    specific, load capacity.


5. Properly used Solon® Belleville Springs & Washers can
    reduce the loss of preload by a factor of 5X or more, and
    greatly reduce the opportunity for a failure.
