A disc spring is a conical shell which can be loaded along its axis either statically or dynamically.
Particular feature: “Highest load in the smallest space”
Effective January 2017 the familiar DIN standards for disc springs („DIN 2092-Calculation of Disc Springs“ and „DIN 2093-Quality requirements, Dimensions“) have been withdrawn.
These solely German standards have now been incorporated into European standards with the aim of securing the availability of high-quality standard disc springs for the whole world market.
- DIN EN 16983 – Quality requirements, Dimensions
- DIN EN 16984 – Calculation.
Disc springs support dynamic processes efficiently and predictably: often under extreme force and load conditions.
Original SCHNORR® disc springs excel by:
- High force in a small area.
- Predictable service life under dynamic load.
- Use of highest quality spring materials.
- Adherence to force and dimension specification.
Materials with the highest tensile strength and utmost elasticity are required to make disc springs.
Materials for disc springs are principally supplied in the following forms:
