Listing ID #3467828

Belleville washer in imperial as well as metric sizes. Belleville washers also called conical spring washers are manufactured as per DIN 6796 & DIN 6908. IIS Belleville washers 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 boltnut assemblies working loose. They do not effectively prevent loosening of the assembly under varying radial 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 loading and infrequent varying load applications. The force give in the table below is approximate.
Conical Spring washers as per DIN 6908 are intended for use with screw and washer assemblies as specified in DIN 6900 part 5.They are designed to use with bolted connections with bolts of property classes 8.8 to 10.9 (as specified in ISO 898 Part 1).
