Metric Belleville Spring Washers

Belleville Spring Washers - MetricA Belleville spring is a conically shaped disc that will deflect (flatten) at a given rate. This spring rate is usually very high, allowing the spring to produce high spring loads in tight spaces. 

Designed and manufactured by an American Belleville spring manufacturer, Solon Manufacturing Co., Solon Belleville conical spring washers are used in a variety of applications across many different environments. These springs are used to maintain bolt preload by preventing bolt tension loss due to differential thermal expansion, high-temperature bolt yield, packing and gasket relaxation, and vibration. Solon Manufacturing manufactures a complete line of Belleville springs and washers for use on bolting applications. They are available in several types of materials and finishes to suit the needs of the end-user.

Available Metric Sizes: 

Belleville springs are available as standard metric sizes from 4mm - 80mm
Flange washers are available as standard metric sizes from 6mm - 110mm
DIN/Solon Disc Springs are available as standard metric sizes from 2.5mm - 125mm
