DIN 2093 divides disc springs into three series based on the ratio of disc height to material thickness. Series A produces a progressive load curve and suits high-load, limited-deflection duties. Series B gives a near-linear response, making it the preferred choice where consistent force across the travel range matters. Series C delivers high deflection at lower loads and fits applications where travel range is the priority. Confirm your required load, deflection, and axial space budget before selecting a series.

You need four key dimensions: bore (inside diameter), outside diameter, material thickness, and free height. These four values, combined with the DIN 2093 series designation, uniquely identify a disc spring. Cross-reference them against your existing component or the original equipment drawing. If you have only a part number from a previous supplier, use Ask Simon on the relevant product page for an instant fitment check before placing an order.

Stacking orientation changes the mechanical output of the assembly. Arranging discs in parallel (nested in the same direction) multiplies the load capacity while keeping deflection equal to a single disc. Arranging them in series (alternating direction) multiplies the available deflection while keeping load equal to a single disc. Many assemblies combine both orientations in groups to tune both load and travel simultaneously. Your stack configuration must be confirmed before specifying quantity.

Yes. Disc springs are listed individually and in trade quantities suited to production and maintenance schedules. If you need a specific pack size or a volume that differs from the listed options, contact the PartsForMachines team directly via WhatsApp 07754288583 or at [email protected] to discuss your requirement. Trade account holders can also request scheduled releases against a blanket order.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Disc Spring

Disc springs (also called Belleville washers) are conical-pressed load elements used wherever a high load must be absorbed, deflected, or preloaded within a very short axial space. They appear in press tooling, valve assemblies, clamping fixtures, gearbox stacks, and safety-relief mechanisms across general engineering, hydraulics, and industrial machinery. PartsForMachines lists disc springs as Authorised Distributor and Seller, covering the ranges found under Spring, Strut and Hardware on the site.

Selection follows the DIN 2093 classification system. That standard defines three series by the ratio of disc height to thickness: Series A for progressive load curves, Series B for near-linear response, and Series C where high deflection with lower load is the requirement. Buyers specify by bore, outside diameter, thickness, and free height, then confirm which series and which stacking configuration the application calls for. Stacking in parallel multiplies load capacity; stacking in series multiplies deflection travel. The product pages carry those dimensional attributes so the right disc can be matched to the assembly without guesswork. It is Metrol product throughout the disc spring here.

Disc springs are wear items in high-cycle applications. In clamping and clutch stacks they fatigue progressively, so periodic inspection of the seating face and free-height measurement is the practical maintenance habit. Pairing replacement disc springs with new seating washers, where the assembly uses them, keeps the stack geometry consistent and load response predictable.
