Pre-Assembled Disc Spring Stack Benefits

Time-Saving Accuracy and Consistency:
Precise stack configuration is guaranteed, eliminating the risk of improper configuration and wasted time resulting from costly rework.  

Construction Time is Eliminated:
Each stack is constructed to precise specifications, eliminating the time required to handle, arrange, and align individual Disc Springs.

Consistent Precision Lubrication:
If lubrication is required, precision and uniform application are essential to the performance of a Disc Spring Stack. Pre-lubricated Disc Spring Stacks are supplied ready for immediate installation, helping reduce assembly time and the need for on-site greasing.

Fully Customizable Stack Design & Packaging:
Pre-Assembled Disc Spring Stacks are configured and packaged to your unique application requirements. Customizations include: Disc Spring material, overall stack height, and more. Optimize your packaging to simplify handling, installation, and storage during production.

Simple Drop-In Installation Reduces Assembly Costs
Each Disc Spring Stack arrives ready to install. This ensures streamlined, predictable, and repeatable results in the final assembly. 

SPIROL’s Application Engineers will help you from start to finish!

Save Time, Money, and Ensure Quality

One of the most demanding and complicated components to construct in a production environment is the Disc Spring Stack. When manufacturers use Pre-Assembled Disc Spring Stacks rather than purchasing single Disc Springs and stacking them in-house, they are easily able to save time and money while ensuring the quality of their final assembly.

    Specifications

    SPIROL manufactures Pre-Assembled Disc Spring Stacks using Disc Springs produced to DIN 16983 standards. These range in size from miniature 8mm outer diameters—ideal for compact or precision mechanisms—to large 200mm diameters, comparable in size to standard industrial flanges or pressure gauge housings.

    Between these extremes, we offer a full range of sizes suitable for applications from precision instruments and automotive components to heavy-duty industrial equipment.

    Application Success Stories

    Disc Spring Stack in Crane Overload Safety Switch

    Customer Challenge:

    A manufacturer approached SPIROL for assistance on designing a stack of Disc Springs that would reliably activate an overload mechanism for a warehouse crane. The designer had a specific range for the crane to function, and the Disc Springs were to activate the overload mechanism preventing the use of the crane at loads over 2700kg (26.48kN). The manufacturer’s design parameters limited the maximum Disc Spring diameter to 94mm and a stack height of 150mm.

    SPIROL solution:

    • SPIROL’s Application Engineering Team determined that (20) alloy steel (51CrV4) Disc Springs (DSC 90 x 46 x 5mm WR) stacked in series would provide the nominal force/deflection requirements within the physical constraints of the design.
    • Disc Springs stacked in series perform such that deflection is a single Disc multiplied by the number of Discs and the force is the same as a single Disc.
    • To ensure the Disc Spring Stack would perform as desired at the minimum and maximum material conditions, SPIROL Engineering’s evaluation included calculating the performance of the Disc Spring Stack at the extreme limits of the tolerance range.
    • In the end, the recommended Disc Spring Stack met all performance requirements within the physical constraints of the design.

    Disc Spring Stack in Mechanical Clutch in Heavy Duty Right Angle Drill

    Customer Challenge:

    The lead engineer at a prominent hand and power tool company contacted SPIROL for help determining the best Disc Spring design for a new lightweight, compact, and portable Heavy Duty Right Angle Drill.

    SPIROL solution:

    • SPIROL Engineering designed two special Disc Springs stacked in series to meet the specific force and deflection requirements.
    • Disc Springs offer a higher load capacity in less space as compared to conventional coil springs which enables the designer to make the tool more compact. 
    • Unlike Belleville Washers that are mostly used in static applications, Disc Springs provide unparalleled predictability, reliability and fatigue life in highly dynamic applications. 
    • By partnering with SPIROL and incorporating our recommendation, the customer minimized costly development time and confidently launched their new high quality drill to the market.

    Disc Spring Stack in Turret Punch Press Assembly

    Customer Challenge:

    Traditional turret punch press tool designs utilize coil springs (die springs) to facilitate the stripping mechanism of a die. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process.

    SPIROL solution:

    • When stacked in series, SPIROL Disc Springs are capable of providing a greater, more consistent stripping force than coil springs and require less space.
    • A coil spring must be seven times larger than the Disc Spring Stack to achieve the same spring rate
    • Disc Spring Stacks have become an instrumental component in the advancement of turret punch press tooling - especially when needing to form thick materials, large extrusions and more complex designs.

    Frequently Asked Questions

    What is the difference between a Belleville Washer and a Disc Spring?
    While the terms Disc Springs and Belleville Washers are often used interchangeably, there are several important technical differences that should be clearly understood by Design Engineers. Belleville Washers are primarily used in heavy duty applications fastened together with a bolt where the load is considered static. Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. Unlike Belleville Washers, Disc Springs are designed specifically to provide a repeatable force-travel relationship, and have a long and predictable fatigue life in dynamic or cycling applications. For a more detailed information, read SPIROL's White Paper: The Difference Between Disc Springs and Belleville Washers.
    What is the life cycle of your Disc Springs?
    Deflection of a Disc Spring at a given load is predictable making it possible to calculate force and stress levels in the Disc. As the Disc Spring flexes, stress levels in the Disc change; the greater the change, the faster the Disc Spring fatigues. For detailed information on how to calculate the cycle life of a specific Disc Spring in a particular application, read: How to Calculate the Estimated Fatigue Life of a Disc Spring.
    Do you offer Disc Springs in sizes/materials not listed in your catalog?
    SPIROL offers complimentary Application Engineering. If your application requires a special Disc Spring, our Engineers will evaluate your application and design a unique part to meet your needs. If you would like SPIROL's Engineers to review your application, click here.
