Spring Washer Applications and Solutions

Joanne Qu 2023-11-09 14:12:36

Vibration, differential thermal expansion, bolt creep and yield, and relaxation can all cause a loss of bolt preload, which leads to loosened joint and bolt failure. Solon Rainbow Spring Washers are compressible and highly configurable fasteners designed for use with bolts, studs, nuts, gaskets, and other industrial components to prevent loosening that leads to bolt failure and fugitive emissions.

Industrial spring washers achieve optimally tight connections in gasket and packing applications and are self-damping with long service life. Features and benefits of Belleville spring washers include:

  • Maintenance of tight bolted connections

  • Use washers individually or stack in series, parallel, or combination configurations

  • Available in imperial and metric sizes

  • Industry standard and exotic material options

  • Maintain bolt preload to reduce bolted joint failures

Harbin Rainbow Technology provides spring washer solutions for a broad range of industries.

General Purpose Bolting: Use to prevent stress caused by vibration and mechanical movement in a range of bolting applications. General-purpose industries include packaging, automation, machinery, manufacturing, and entertainment.

  • Commercial Applications:  Industries include heavy equipment, packaging, aerospace, manufacturing, transportation, pulp and paper, and medical.

  • Electrical Connections:  Use to maintain bolted connections and prevent hot spots that lead to arc flash or catastrophic failure.

  • Valve Live Loading: Prevent valve leaks that lead to fugitive emissions with Flange Washers.  

  • Cryogenic Flange Live Loading: Use cold temperature resistant flange washers for valve live loading applications in cryogenic environments.  

  • Elevated Temperature Flange Live Loading: High temperatures and thermal cycling cause stress on flange joints. Prevent tension loss and fugitive emissions with Flange Washers.

  • Structural Bolting: provide stability and flexibility required to ensure joint integrity in structural applications.

  • Environmental Bolting:  Corrosion and weather resistant Flange Washers maintain bolt integrity in natural and artificial environments involving corrosive substances.

  • High Cycle Applications: Use  in high-cycle applications where there are issues with fatigue and changes in stress.
