Mubea - Disc Springs for Industrial Applications

Mubea is a specialist in the field of spring technology. Mubea offers top quality disc springs together with internally and externally slotted disc springs and wave springs.

Disc springs are used in a large variety of industrial applications, ranging from safety valve systems placed 3000m below sea level to satellites in outer space.

Disc springs (in compliance with DIN 2093 and our own internal standards) are permanently available in stock. Mubea provides customers all over the world with the highest possible quality in all areas of spring technology.

DISC SPRINGS

Disc springs are shallow conical rings that can be subjected to axial loads and in general have a constant ring thickness. The load is evenly distributed over the upper inside and lower outside edge. Generally manufactured from spring steel they can be subjected to static, rarely alternating and dynamic loads. Disc springs fulfil the most stringent requirements for fatigue strength and against setting loss.

Disc springs have the following characteristics; high fatigue life and low creep tendency with the correct dimensioning, high load capacity with a small spring deflection and considerably better space utilisation when compared with other types of springs. Different assemblies can be designed to achieve the desired load characteristics and special materials and various surface coatings can be used.

SLOTTED DISC SPRINGS

Internally or externally, slotted disc springs have a dimensional range of 20-300mm and are produced for overload couplings, automatic transmissions and couplings.

Through the use of special production processes the highest demands for load tolerances and fatigue life are met. Slotted disc springs are developed in collaboration with customers for specific applications.

PHOSPHATED CONVENTIONAL DISC SPRINGS

Conventional disc springs have an outside diameter of 8-800mm, are phosphated and oiled as standard, and are shot-peened to improve fatigue life if they have a thickness of less than 0.5mm. Areas of application include:

• Safety brakes for lifts, elevators, and construction and railway vehicles
• Backlash compensation for ball bearings
• Vibration isolation, etc
• Boiler suspension systems in power stations
• Safety valves
• Overload protection in electric transformers
• Couplings: Aerial cable cars: Machine tool clamping components

As a standard process shot-peening is especially advantageous in dynamic spring loading applications requiring a long lifetime. Furthermore, extremely well equipped laboratories are available to meet customers' testing requirements.

WAVE SPRINGS

Wave springs are manufactured with a dimensional range of outside diameter 20mm to 300mm. Wave springs are frequently used to improve gear shift quality in automatic transmissions. Designed to meet individual customer requirements, areas of application include backlash compensation and automatic transmissions.

IN-HOUSE MANUFACTURE

All products are manufactured in-house starting with the production of basic materials in our own cold-rolling mill. All tooling is designed, manufactured and maintained in-house. Mubea permanently stocks a variety of antimagnetic, corrosion- and heat-resistant materials for special applications, in addition to 50 CrV 4 (SAE 6150), providing Mubea with flexible production processes, which enable quick responses to customer needs.
