Our team at BelleFlex™ has decades of experience in designing and manufacturing Belleville solutions for markets worldwide. BelleFlex™ Belleville disc springs are used to pre-load bearings for a variety of applications, such as transmissions, clutches, and brakes. These components, used commonly in vehicles, heavy equipment, and trains, are important to daily operation in aerospace, transportation, manufacturing, and construction. Our flange bolting, available in 15,000 to 60,000 psi bolt stress, reduces leakage and extends application life in pipelines, valves, and pumps. Products, like bus bars and transformers, rely on BelleFlex™ Bellevilles to keep joints tight, maintain bolt pre-load, and increase the elasticity of fastening systems.

We supply Bellevilles that meet the needs of many markets, including Bellevilles that are corrosion resistant, can withstand high temperatures, can withstand high loads, or can optimally perform in cryogenic temperatures. Using materials, like H13 Tool Steel, 300 Series Stainless Steel, and INCONEL Alloys, we manufacture Bellevilles for high temperature applications, such as those in manufacturing, oil refining, transportation, and downhole drilling.

Our Bellevilles, properly installed, promote long life for your equipment under the most difficult and challenging circumstances. Follow the links on the left to learn more about how BelleFlex™ Belleville disc springs are used in selected markets.
