Metric Belleville Spring Washers

A Belleville spring is a conically shaped disc that will deflect (flatten) at a given rate. This spring rate is usually very high, allowing the spring to produce high spring loads in tight spaces. Designed and manufactured by Solon Manufacturing Co., Solon’s ISO 9001:2015-certified Belleville conical spring 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. They are available in several types of materials and finishes to suit the needs of the end-user.

Metric Belleville Washer Features

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. Solon’s metric Belleville washers are conical, with centers that are raised into a cone shape. This cone shape is what gives a Belleville spring its heavy-duty strength. Long service life, self-damping, and efficient use of space are among the common characteristics of all Solon Belleville metric washers & washer products.

Additional Metric Belleville Spring Advantages

High spring force with small deflections
Absorbs shock and compensates for vibration
Predictable load-deflection curves where straight, progressive or regressive characteristics are required
No deformation or fatigue under normal conditions

Metric Belleville Washer Applications

Designed and manufactured by an American Belleville spring manufacturer, Solon Manufacturing Co., Solon Belleville conical spring washers are used in a variety of applications across many different environments. Specific uses include but are not limited to:

Achieving Belleville Washer & Disc Spring Load & Deflection

Washers and disc springs can be stacked in a variety of configurations in order to achieve greater – or more specific load capacity, they include:

Single, one spring
Parallel, all springs are stacked the same way
Series, all springs stacked opposing each other
Parallel-Series, a combination of the two
