Why More Design Engineers Are Specifying Spirolox Compression Wave Springs

Instead of conventional round wire springs, coil springs, or wavy washers, more and more design engineers are specifying compression wave springs for dimensional variations in tight radial dynamic conditions. Reason: compared to those alternatives, compact wave springs save space and provide more precise load deflection characteristics. This allows engineers to design smaller assemblies with lower frees lengths and /or lower operating heights - sometimes by as much as 50% - while improving deflection characteristics.
And today, more and more design engineers are specifying Spirolox wave springs for two very good reasons.

First, we maintain a large supply of all popular sizes of wave springs that are ready for delivery within 24 hours of ordering. This off-the-shelf delivery means on-time assembly for you, and on-time shipments for your customers. What's more, we maintain a nationwide network of over 900 distributors. That means you can get the wave springs you want, in the quantity you want, where your want, and when you want. In short, Spirolox offers faster delivery and better service.

The other reason design engineers prefer Spirolox is because they know that as an ISO 9001-certified company, our quality assurance program in second-to-none. Achieving ISO certification in no small task, and Spirolox takes great pride in this accomplishment. And in many ways, it's a natural extension of our entire quality program. ISO 9001-certification - one of the most sought-after quality certifications by companies around the world - means that we not only meet our own quality standards, but our quality assurance programs also meet the standards of external auditors.
In practical terms, ISO certification means greater internal operating and manufacturing efficiencies, which is your guarantee that our products consistently meet high-quality standards. Of course, our customers have always been assured of that. But now it's officially certified!
Certification of conformance for materials used and/or finished parts is available upon request. Certification for special design requirements can also be requested when orders are placed.

WAVE DESIGN CONSIDERATIONS
Specific wave springs applications are extremely diverse. However, there are common denominators shared by most designs that can help you determine which wave spring best suits your needs. They are design envelope, load requirement, and operating conditions.
Design envelope - The design envelope usually consists of a bore in which the spring operates and/or a shaft which the spring clears. The spring may pilot the bore of the shaft, depending on the application. Bearing pre load springs are designed to lightly contact the bore. Other wave springs "float" between the bore and the shaft.
All wave springs are designed with diametral expansion in mind to prevent interference with a shaft. The distance between the loading surfaces defines the operating height of the spring.
Load requirement - The load requirement may be stated in one of three ways:

1. A load requirement at a specific working height.	2.The minimum load requirement at one working height, and a maximum load requirement at another working height.
3. The specified spring rate between the minimum and maximum working heights.
