It should be noted that if critical force-versus-deflection linearity is required, only the center 60-80% of the available deflection range should be employed. Thus, reserve at least the first and last 15-20% of the range for potential spring-end and adjacent coil-contact effects. These effects can be largely ignored for the majority of spring applications.
The “Suggest Maximum Deflection” used in our online and print catalog reflects the recommended inches of travel to obtain a statistical service-life of approximately 100,000 cycles(deflections) with infrequent breakage. This can be realized if the spring in question is not subjected to shock loads, rapid cycling, temperature extremes, corrosion, or stress values above those recommended. If the spring is statically loaded (not cycling), a near-infinite life can be expected. Extended spring service-life can be achieved through shot-peening. Our custom spring department can advise you regarding this procedure.
The highest grades of spring wire are used when fabricating our springs. To create cost-effective warehousing of our stock spring inventory for our customers, we offer material certification as custom springs only. Certifications of conformance for geometric tolerances set by the Spring Manufacturers Institute (SMI) are available for our stock springs upon request.
The term “spring steel” is a stock inventory term covering music wire, hard-drawn(MB) wire, and oil-tempered wire. Additionally, stock compression spring materials may include stainless steel (300 series), beryllium copper, and phosphor bronze.
Shama Spring manufactures our stock springs to commercial tolerances, as defined by the SMI. Calculated rates and loads based on SMI geometric tolerances have an approximate +/- 10%. Low or high-index springs will have higher values. Compression springs characteristically have an hourglass shape when coiled on an automatic coiler; therefore, outside/inside tolerance is applied to end coils only. This is an improvement consideration when selecting a spring that fits over a rod or inside a cylinder. Call us if tighter tolerance values are required for your application.
Our stock compression springs contain a selection of commonly requested finishes:
- Zinc (upon request)
- Gold Irridite (upon request)
- Black Oxide (upon request)
- Passivated (upon request)
- None (can be plated upon request)
Available Size: 0.10-12 mm
