What Mubea Disc Spring Division does

Mubea Disc Spring Division is the disc spring (Belleville washer) manufacturing arm of Mubea, a family-owned German industrial group founded in 1916 and headquartered in Daaden, Germany. The division has manufactured disc springs for over 40 years at its Daaden production facility, with full vertical integration from raw material (operated through its own cold rolling mill up to 6mm) through fine blanking, heat treatment, shot peening, deep rolling, and corrosion-protective coating to finished springs. All disc springs are produced to EN 16983 (DIN 2093) standards, with the proprietary Generation II deep rolling process enabling up to 10x extended fatigue life and up to 33% installation space reduction compared to standard Belleville springs. The product portfolio spans 8mm to 800mm outer diameter Belleville disc springs, slotted, wave, and special disc springs, self-centering spring stacks, and a broad materials range including standard spring steels (51 CrV 4), corrosion-resistant, thermally stable, antimagnetic, and high-temperature Inconel alloys for service up to 500°C.

The division serves manufacturers across seven primary verticals: automotive (transmissions, clutches, brakes, suspension), oil & gas (subsea valve actuators, drilling), railway, powersports, off-highway/agricultural, energy (wind turbines, power plants), and industrial/machine tool applications. North American coverage is delivered through a stocked distribution and sales hub in Florence, KY, which holds over 300 catalog sizes and supports JIT delivery to the United States, Canada, and Mexico. The commercial model is quote-based B2B sales with engineering support and custom design assistance, including stack pre-assembly and a disc spring calculator tool for force and life analysis. The customer base is enterprise — as evidenced by GM Supplier of the Year (2018), Daimler Innovation Award (2018), and Airbus Top Supplier recognition — with safety-critical applications in subsea, transmission, and aerospace driving recurring demand. The parent Mubea group employs over 13,000 people across 30 offices globally, and the division itself maintains ISO/TS 16949, ISO 9001, and ISO 14001 certifications.

Differentiator

Problem solved

Functional benefit

Brands

• Generation II Disc Springs: High performance disc spring technology that allows springs to operate at higher stress levels, providing higher durability and reduced overall size with fatigue life increased up to 10 times compared to standard Belleville springs.
• Self-Centering Disc Spring Stacks

Products and services

• Disc Springs (Belleville Washers) Conical-shaped washers that function as springs, capable of supporting high loads with relatively small deflections. Manufactured by Mubea to EN 16983 (DIN 2093) specifications, offered in sizes from 8mm to 800mm outer diameter. Used by industrial OEMs across automotive, oil & gas, railway, energy, and machine tool sectors.
• Belleville Washers Coned shape washers used as springs in high-load applications. Another name for Mubea disc springs for industrial OEM customers.
• Slotted Disc Springs Disc springs with slots cut into them, commonly used as piston return springs for clutches in automatic, CVT, and dual clutch transmissions. Designed for automotive OEM and Tier 1 customers.
• Wave Disc Springs Disc springs with a wave configuration, used in industrial applications requiring specific load characteristics.
• Special Disc Springs Custom-designed disc springs for couplings, gearboxes, transmissions, and applications requiring special fitting requirements. Manufactured via stamping, turning, fine-blanking, cold/hot-forming, laser-cutting, or water-jet cutting for industrial OEM customers.
• High Performance Generation II Disc Springs Next-generation disc spring technology allowing operation at higher stress levels than standard Belleville springs, providing up to 10x increased fatigue life, up to 25% diameter reduction, and up to 33% installation space reduction.
