Belleville Springs has a complete range of precision disc springs designed to DIN 2092 and manufactured to DIN 2093, designed for critical loading or dynamic applications.
DIN 2092/2093 disc springs are manufactured to close tolerances and are made from high quality spring steel strip and forgings.
The standard protective surface treatment is phosphate and oiled, however superior surface treatments should be considered for disc springs that are to be situated in hostile environments.
The disc springs are pre-stressed (scragged) and the machining and radiusing of the inside and outside diameters remove stress raisers, which could otherwise reduce disc spring fatigue life.
The DIN 2093 specification classifies disc springs into three groups:
Group 1; 1.25mm up to and inc. 6mm: cold formed-machined (or fine blanked), radiused edges, without contact flats
Group 2; Under 1.25mm thick: cold formed, radiused edges, without contact flats
Group 3; Over 6mm thick: Fully machined from forged blanks, with contact flats, thickness reduced
