CUP WASHER

cup wasgerCup Washers are also known as Belleville washers. These are typically used as springs, or to apply a pre-load of flexible quality to a bolted joint or bearing.

Some properties of Cup Washers include: high fatigue life, better use of space, low creep tendency, high load capacity with a small spring deflection and possibility for high hysteresis (damping) by stacking several washers on top of each other in the same direction. They may also be used as locking devices, but only in applications with low dynamic loads, such as down-tube shifters for bicycles.
