Description

Do you need a disc spring, also known as a Belleville washer, that performs reliably even in humid, salty, or chemically harsh environments? DIN 2093 disc springs in stainless steel AISI 301 (1.4310) are built to resist corrosion and maintain their spring force over a long period. The material is a stainless spring steel with high elasticity and tensile strength, making the spring well-suited for applications with high mechanical loads and frequent cycles.

Disc springs according to DIN 2093 provide very high spring force within a short installation length, making them indispensable in joints, couplings, and constructions where space is limited but reliable spring action is required.

AREA OF USE

Perfect for pre-tensioning bolted joints, bearings, couplings, and brakes in machine construction, offshore, marine environments, the energy industry, and food production. The conical disc shape allows the spring to be mounted individually or in stacks to achieve the desired spring force and stroke. Installation is simple, and thanks to the stainless material, the spring requires minimal maintenance even during continuous operation in corrosive environments.

FREQUENTLY ASKED QUESTIONS (FAQ)

How does a DIN 2093 disc spring work and what is the advantage of its compact shape?

DIN 2093 defines the standard for conical disc springs that generate very high spring force in the axial direction with very short travel. The compact design allows you to achieve extremely high pre-tensioning forces in tight spaces where conventional coil springs cannot fit, such as in brake systems, couplings, valves, and heavily loaded bolted joints.

Why is stainless spring steel AISI 301 (1.4310) used instead of regular stainless steel?

Standard stainless steel (such as A2/A4) has excellent corrosion resistance but lacks the high yield strength required for repeated, heavy spring cycles. AISI 301 / 1.4310 is a cold-drawn, stainless spring steel with high elastic deformability and fatigue strength. It gives the spring the ability to rebound distinctively without permanent deformation, while resisting rust in humid and demanding environments.

How can you stack disc springs to change force and travel?

Disc springs offer unique flexibility because they can be combined in spring stacks based on the application's needs:

  • Parallel stacking (nested): Increases the spring force proportional to the number of springs without increasing the travel.

  • Series stacking (back to back): Increases the total travel while the spring force remains the same as that of a single spring.

  • Mixed stacking (combination): Provides both increased force and increased travel for customized spring characteristics.
