  • 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.
