Mubea - Disc Springs and Steel Clamping Components

Mubea provides the highest possible quality in all areas of spring technology. Mubea offers you top quality disc springs with an outside diameter of up to 800mm, together with internally and externally slotted disc springs and wave springs. Mubea's other area of expertise is the production of complex precision stamped parts and high-quality clamping components.

DISC SPRINGS

The versatility of disc springs allows for a large variety of industrial applications, from safety valve systems placed 3,000m below sea level to satellites in outer space. (in compliance with DIN 2093 and our own internal standards) are permanently available in stock.

Starting with the production of blank materials in our own cold-rolling mill, all products are manufactured in-house. Moreover, 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.

DISC SPRINGS - SPRING STEEL PRODUCTION

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.

Disc springs are generally manufactured from spring steel and can be subjected to static, rarely alternating and dynamic loads. Disc springs fulfil the most stringent requirements against setting loss and for fatigue strength. Disc springs are set apart from other spring types due to the following characteristics:

• High fatigue life and low creep tendency with the correct dimensioning
• Different assemblies can be designed to achieve the desired load characteristics
• Special materials and various surface coatings can be used
• Cost-effective as a result of standardised sizes
• High load capacity with a small spring deflection
• Considerably better space utilisation when compared with other types of springs

SLOTTED DISC SPRINGS - OVERLOAD COUPLINGS

Internally or externally, slotted disc springs have a dimensional range of 20-300mm and are produced for the following areas:

• Overload couplings
• Automatic transmissions
• Couplings, etc

Specifications:

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

CONVENTIONAL DISC SPRINGS - CONSTRUCTION BREAKS

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

Mubea produces wave springs with a dimensional range of outside diameter 20 mm to 300 mm. Wave springs are frequently used to improve gear shift quality in automatic transmissions. Wave springs are designed to meet individual customer requirements. Areas of application include:

• Backlash compensation, etc
• Automatic transmissions
