A Belleville Washer, also known as a Conical Spring Washer, Disc
Spring Washer, Belleville Spring Washer or Cupped Spring Washer, is
a type of spring that is shaped like a washer. It's shape gives the
washer a spring characteristic. The benefits of Belleville washers
include a long service lie, no setting or fatigue under normal loads
and stresses, low creep tendency, high load capacity, efficient use
of space and high spring forces with low spring height. Belleville
washers can be stacked to modify the spring constant or the amount
of deflection to better meet a variety of application needs.
Belleville washers are available in
spring
steel,
stainless
steel and
410
stainless steel.
