[Head supporting springs for hard disk drives]

In hard disk drives, stainless steel precision thin sheet springs are used to keep a magnetic head floating at a distance of about 10nm above a disk surface spinning at high speeds. We offer a high level of precision, requirements for HDD suspension running at just }1.0mN for load and }0.3 degrees for static angle.
Suncall is also developing in-house design products and promptly making the optimum shape to fit user specifications, utilizing FEM and Modal analysis.
