Belleville Disc Springs

belleville disc springsBelleville springs, also known as Belleville washers or disc springs, were invented by Julien-Francoise Belleville, who was awarded a patent in 1861 for a spring designed like a cone-shaped ring, capable of absorbing large axial forces with relatively small spring travel. From the term Belleville spring, many variations have been derived. The springs are also commonly referred to as Belleville washers, Belleville spring washers, disc springs, disc spring washers, spring washers, coned springs, cup washers, and ball bearing springs. All Mubea disc springs are manufactured to the DIN 2093 standard.

Disc Spring Applications

Belleville springs have become indispensable in a host of applications and industries. Belleville disc springs are used everywhere from the automotive, food processing, and chemical industries and found in applications from boilers and industrial furnaces to superconductors and satellites.

They are commonly used in applications requiring high spring force and small deflections. The washers are also used in applications requiring a high degree of safety. 

Mubea has manufactured Belleville springs in our Daaden, Germany plant since 1960.
