Belleville washers play a crucial role in ensuring secure and long-lasting electrical connections. When installed correctly, they maintain consistent clamping force, reducing the risk of loosening due to thermal expansion, vibration, or material creep. In this guide, we’ll outline the recommended methodology for installing Belleville washers for electrical connections to help electrical contractors maximize performance and reliability.
You must know how to calculate torque for tightening bolts to ensure that your application is functional and safe. Errors in torque calculation can result in expensive failure, including the time and hassle of replacing broken equipment. Having the wrong materials, or an incorrect torque calculation can be potentially hazardous. An under-torqued bolt will deform and won’t be able to provide as much clamping force as needed, while an over-torqued bolt will break.
Our material selection will accommodate working temperatures from -400 deg. F to 1100 deg. F, various corrosive environments and magnetism requirements.
Our Flange Washer line adds deflection to bolted joints, in order to dramatically reduce the effects of large fluctuations in temperature within the application.
Governed by the specifications outlined in the European DIN EN 16984/16983 (formerly DIN 2092/2093), they are engineered and manufactured to perform as needed in the most arduous dynamically loaded spring applications.
