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 Springs

A disc spring is a conical washer that flattens under load and pushes back as it does, and the 150 on this shelf are picked on three dimensions to the DIN 2093 standard: outer diameter, inner diameter and material thickness, running from small 10 millimetre discs at 0.4 millimetres thick up to 100 millimetre forms in gauges reaching 6.55.

The stack is where the engineering happens. A single disc on its own gives very high force over tiny travel; stacked in series, cone to cone, the travels add together; stacked in parallel, nested facing the same way, the forces add instead; and series-parallel stacks tune both at once, so one catalogue of graded washers becomes almost any spring the available space allows. That is why disc springs live where coil springs cannot fit, under bolt heads, inside clutches, clamps, presses and valve assemblies, anywhere serious force must fit inside just millimetres of available height, delivered by a washer instead of a coil.

The same outer and inner diameter pairs come in stepped thicknesses across the shelf, the 100 by 51 millimetre body in five gauges among them, because thickness sets the force in a disc: thicker discs push harder over the same travel, so the seat picks the two diameters and the duty then picks the gauge between them.

The three DIN dimensions typed into search find the disc directly on the shelf, a worn stack measured, counted and noted for arrangement rebuilds itself like for like, and a photo of the stack with its measurements over WhatsApp on 07754288583 comes back with the disc named, the count confirmed and the series-parallel arithmetic checked for the duty.
