Mubea Incorporated is a wholly owned subsidiary of Mubea.  All Mubea disc springs, belleville disc springs or spring washers are manufactured in Daaden, Germany where they have been produced for more than 40 years, combining years of experience with updated quality control methods.  Mubea Incorporated keeps an extensive stock and sells the disc springs out of our Florence, KY plants to the North American market. 

Mubea disc springs are used in many types of applications.  These applications range from industrial applications, such as safety valve systems placed 3000 m below sea level, to satellites in outer space.

A team of highly qualified engineers will work to find individual solutions to every spring problem by utilizing ongoing development of technologies, creativity, and an innovative approach. In addition to the strong engineering support, testing requirements can also be met with our extremely well-equipped laboratories.

Advanced Production

Mubea maintains high internal production standards to ensure a good quality level and economic efficiency through innovative and rigorous production methods, starting with the cold rolling of our own material to very tight tolerances.

Dependent upon spring thickness, blanks are manufactured by conventional stamping (Group 1), fine blanking (Group 2) or plasma arc/flame cutting (Group 3). High thickness springs are machined all over to remove surface imperfections. Depending on the requirement, disc springs can be heat-treated to achieve a martensite or bainite grain structure to extremely tight hardness tolerances. Shot-peening is performed on the parts to improve fatigue life. Phosphating and oiling is the standard corrosion protection and is done in house.

Continuous monitoring of the production steps guarantees the high quality of Mubea disc springs.
