At BelleFlex®, every Belleville disc spring we manufacture meets or exceeds customer specifications, even for the most demanding applications. In both mass production and custom design, we employ the standard calculations of DIN 2092 to create a disc spring with predictable deflection for a given load. Our disc springs may be used singly or  stacked in series, in parallel, or in parallel sets in series. We provide certificates of compliance free-of-charge and additional certifications are available to meet your requirements.
