　　The spring characteristic (linear, positive or negative) can be engineered to a large extent by means of changing the disc spring properties (dimensions, adding slots on inside or outside, stacking, etc.)

　　Very slight spring deflections can be achieved by use of single springs.

　　Using disc springs in series, spring deflection increases, without materially affecting the forces involved.

　　They can be combined into groups of serial and parallel order in the same stack for special applications.

　　Disc springs show a symmetrical buildup of forces around the rotating axis, with this symmetry being maintained throughout the lines of the spring equally.

　　They show a circular, symmetrical transmission of forces in the exact direction of the spring axis - this being directly in contrast to actions of coil springs.

　　They permit the use of the smallest possible

　　working area - this being notably in contrast to the space required to accommodate the "dead windings" of a coil spring.

　　Disc springs are characterized by high forces resulting from moderate spring deflections - in direct contrast to other spring types.
