Load values are the expected values of various loads such as concentrated force F, pressure p, or moment M acting on metal bellows and other elastic elements. In the use of metal bellows elastic elements, in addition to the given load value, but also must be given the direction and location of the load. For pressure loads, it is also explained that the elastic element is subjected to internal or external pressure.

The value of full load or full range that metal bellows and other elastic elements are allowed to use under normal working conditions, usually the expected design value or the design value that is modified after actual testing of the product prototype.

The carrying capacity of a specific elastic element product that is allowed to exceed its rated load in a moment of operation or during testing without damage, failure, or instability. For instrument elastic sensitive elements, the overload capacity is generally limited to 125% of the rated load. Bellows class components used in engineering are generally limited to 150% of the rated load. According to the engineering requirements, when large safety factor is required, the elastic element used is not allowed to have any overload, so the load must be less than or equal to the rated load value.
