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
