Disc Springs


Click here to download more information about our Disc Springs.

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”

Manufactured acc. to DIN 2093 and to works standard, using all suitable non-galvanic surface treatments as well as in custom-sizes and from special materials.

These features have created for the SCHNORR® disc spring such a wide variety of applications that there is almost no technical area known in which they could not be used effectively.

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:

Carbon Spring Steel per DIN EN 10132-4

  • C67S – Ref: AISI 1070
  • C75S – Ref: AISI 1078

Chrome Vanadium per DIN EN 10151

  • 51CrV4 – Ref: AISI 6150

Corrosion Resistant Steel per DIN EN 10151

  • X10 CrNi 18-8 – Ref: AISI 30301

The characteristic features of Original SCHNORR® Disc Springs

  • Depending on the spring dimension the load deflection curve can be linear, regressive or progressive.
  • Optimal use of space and utmost spring load with minimum deflection (very high loads in the smallest of spaces).
  • Considerable dampening especially when stacked.
  • Minimal relaxation occurs provided the permissible stress is not exceeded.
  • Highest life cycle with dynamic loads

Heat Resistant Steels per DIN EN 10269 or 10088-2

  • X22 CrMoV 12-1
  • X39 CrMo 17-1

Nickel and Cobalt Alloys

  • Inconel 718
  • Inconel X750
  • Nimonic 90
