Manufactured in the USA since 1949, Solon Belleville Springs and washers are highly configurable products that are used in conjunction with complementary hardware (bolts/studs and nuts) as well as other industrial components, such as gaskets and packing material to achieve an optimally tight connection where high spring loads are desired. Bolted joints loosen due to a variety of reasons. The loss of bolt preload is one of the most prevalent. Solon Belleville Springs and washers reduce bolted joint failures by maintaining the bolt preload. They are particularly useful where vibration, differential thermal expansion, relaxation and bolt creep, and bolt yield are problematic.
Use our new bolt load web tool to calculate bolt load based on bolt type, size, lubricant, torque value, and unit of measure. We also have a torque calculator to help you determine torque value based on inputs relative to bolt type, size, lubricant/condition, and load. Both tools are provided at no cost to help you select your Solon Belleville Spring and Washer products.
CHOOSING A SOLON BELLEVILLE SPRING OR WASHER
Belleville springs and washers are used in a variety of applications across virtually every industry that maintains bolted connections. The washer is not an insignificant engineering contribution—by combining washers in stacks or series or including them in other bolt assemblies, longer service life, lower maintenance and high levels of equipment dependability and safety are realized. Solon offers thousands of catalog washer options—sizes ranging from #4 screw to 4 inches available in both Imperial and metric sizes. With industry-standard and exotic material options, Solon Manufacturing provides a washer solution for every requirement. Our vertically-integrated approach to manufacturing makes Solon custom-friendly. Submit your drawing or contact an application engineer to discuss your needs.

SOLON BELLEVILLE SPRING & WASHER ADVANTAGES
- Maintain bolt preload under normal conditions
- 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
