Disc Springs FeTech Disc Springs are similar to belleville springs with a frusto-conical shape and are typically used for critical loading or dynamic applications. Some properties and advantages of FeTech Disc Spring are including:
high load capacity with a small spring deflection
increased fatigue life
tight raw material specifications
better use of space
lower creep tendency with better heat treatment
narrow tolerances of spring geometry and load
Specifications
European DIN2093 standard disc springs
Customizing off-standard disc springs: outer diameter from 6mm up to 800mm and thickness from 0.2mm up to 50mm that depends on different materials.
Materials Standard Material: 50CrV4… Corrosion Resistant Alloy Steel: SUS316/SUS631/Incoloy825… Heat-stable Alloy Steel: 30WCrV17-2/X40CrMo5-1… Antimagnetic and Corrosion Resistant Alloy: CuBe2… Nickel and Cobalt Alloy Steel: Inconel X-750/Inconel718/Nimonic90…
