IIS Manufactures and Stock Belleville Washers in Imperial as well as Metric Sizes. Belleville Washers are also called as Conical Springs Washers and are made as oer DIN 6796 and are designed specifically for Heavy Duty Bolted Section such as Bus Bars, Transformers, Rectifiers, Heat Exchangers, Transmission, etc. These Washers are intended to counteract the effect of setting which results in Bolt/Nut Introduction of Belleville Washers Metric working Loose. They do not effectively prevent loosening of the assembly under varying Redial Load and are designed for use with short bolts predominantly subject to thrust.
Belleville Washers are High Stressed Components and cannot be used for Dynamic Load and infrequent varying load applications. The force given in the table below is approximate.
