Disc Springs

Custom Disc Springs Designed for Your Application 

SPIROL has the expertise to design and manufacture custom Disc Springs, including Disc Spring prototypes, to meet your precise application requirements. When you involve SPIROL early in your design process, many requirements can be fulfilled with our standard Disc Springs, saving you time and reducing costs. 

For applications that require a Disc Spring that fall outside the DIN 16983 standard product range, SPIROL’s Application Engineering Team will collaborate with you to develop a custom Disc Spring solution tailored to your performance, dimensional, and environmental requirements. 

With decades of experience in Disc Spring design and manufacturing, SPIROL can produce components with custom diameters, thicknesses, force ratings, and deflection characteristics to match your application requirements. 

We offer a wide selection of materials, including 301 stainless steel, 17-7 stainless steel, carbon steel, and alloy steel. Additional materials can also be evaluated based on your unique requirements. A variety of finishes — such as mechanical zinc, black oxide, and other industry-standard coatings—are available to optimize performance and durability.

Application Success Stories

Custom Disc Spring for Pre-Assembled Stack in a Surgical Torque Limiter

Customer Challenge:

A medical device manufacturer approached SPIROL to help to reduce costs and simplify the assembly process of a Disc Spring stack used in a high-speed torque limiter surgical instrument.

SPIROL solution:

  • SPIROL’s Application Engineers reviewed the manufacturer’s performance requirements and assembly challenges with the current Disc Springs while considering the cost-reduction initiative and designed a custom Disc Spring.
  • The custom Disc Spring was designed with a higher cone height than the standard Disc Spring which created greater force in a smaller area.
  • This enabled the stack to contain two (2) fewer Disc Springs than the manufacturer’s original design. With fewer parts in each stack, an immediate cost saving was realized.
  • The custom stack design lowered stresses in the final assembly leading to longer life cycles for the device.

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.

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.
