Because of their versatility, disc springs are used extensively in a variety of applications, from safety valve systems 3000 m under the sea to satellites in space. Mubea stocks disc springs manufactured per the requirements of DIN 2093 as well as their own internal standards. Mubea is capable of producing conventional disc springs with outside diameters up to 800 mm, internally and externally slotted disc springs, and wave springs.

Standard Product Range
The Standard Product Range of disc springs (sizes to DIN 2093 and Mubea Factory Standards) includes 246 sizes with outside diameters between 8 and 250 mm.These springs
are manufactured from Ck 67 and 50 CrV 4, and are typically available from stock. The standard corrosion protection is zinc phosphating and oiling.

Special Range

The Special Range of non-standard disc springs includes 153 sizes with outside diameters from 70 to 600 mm. These springs are typically available from stock. Production tooling is available for these sizes. The standard corrosion protection is zinc phosphating and oiling.

Disc Spring Stacks

On request, Mubea can deliver disc springs pre-assembled in stacks or on a guiding
device. Advantages include:

• Ability to provide stack specific load-deflection diagrams (Mubea load testing machines can measure loads up to 1000 kN)
• Small load tolerances possible
• 100% load testing can be used to verify proper stacking
• Assembly is more efficient with preassembled stacks

Internally or externally slotted disc springs

• Size range: outside diameter 20 to 300 mm
• Slotted disc springs are typically developed in close collaboration with customers for specific applications
• Special production processes are used to maintain extremely tight load tolerances and to achieve the maximum possible fatigue life.
