Prevent Bolt Fatigue Failure With Belleville Spring Washers

High-Cycle and Fastener Fatigue Solutions

Bolted connections are often subjected to cyclical loading which can cause self-loosening or lead to fastener fatigue and loss of bolt preload. Solon Manufacturing Co.’s Belleville Springs are specially manufactured to reduce bolt fatigue and prevent stress-related failures in bolts. They are ideal for high cycle applications subject to fatigue issues, changes in stress, and millions of cycles.

Our ISO 9001:2015-certified Belleville Spring washers are made from high performance materials and multiple finish options for improved durability and corrosion resistance. Solon Belleville Spring Washers have a high spring rate, resolve thermal expansion and produce extremely high loads in a small area.

The Importance of Preventing Bolt Fatigue Failure

Over time, bolts stretch and lose their load due to a variety of reasons. Failure of the bolted joint in many cases can cause downtime for costly equipment repairs or be catastrophic. Bolt fatigue can be caused by several issues contingent with high cycle applications, including:

High-duty cycle
Machine element
CNC tool changer
Cyclical loading

Belleville Springs Prevent Bolt Failure

Expert Manufacturing: All Solon Disc Springs are subject to exacting manufacturing and quality control standards. Additionally, all our DIN spec disc springs and Belleville disc spring washers are preset so that they will not significantly relax under load over time.
High Quality Material: DIN & Disc Spring Washers are available in Carbon Steel, 17-7 PH Stainless Steel, 301 Stainless Steel and Inconel.
Superior Finish: Carbon steel disc springs are finished with the standard corrosion protection of phosphate oil.
Conical Design: Solon utilizes a conically shaped disc that deflects (flattens) at a given rate. Conical spring washers have a high spring rate, resolve thermal expansion and can produce extremely high loads in a small area.

Find The Right Belleville Spring Size to Prevent Bolt Fatigue Failure

Imperial Washers

Belleville springs are available as standard imperial sizes from 7/64” to 2-1/2” ID
Flat washers are available as standard Imperial sizes from ¼”-2” ID
Flange are available as standard Imperial sizes from 3/8”-4”

Metric Washers

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

DIN/Disc Springs

Solon DIN/Disc Springs (SDS) conform to the DIN 2093 specifications and are RoHS complaint. These springs are effective when a large number of deflection cycles or forces are critical.

Additional DIN Spring & Disc Spring Features

Solon Belleville DIN and standard disc spring washers withstand extreme temperatures. American-made Belleville springs are effective when a large number of deflection cycles or forces are critical. Carbon steel disc springs are finished with phosphate oil for improved corrosion resistance in demanding environments. Whether you have a custom material specification or unique application challenges, Solon’s full-service design engineering and production teams can help you with your requirements. DIN/Disc Springs absorb shock, provide dampening, and support high tension in bolted applications.
