Economical solutions for less critical applications

75 different sizes in stock from 4.75mm up to 63.5mm outside dia.

Belleville washers are a more economical and less precise form of conical disc spring, best used for static applications where some setting and/or loss of force can be tolerated.

Belleville washers, manufactured from steel strip, are not scragged (pre-stressed) during the manufacturing process and the inside and outside diameters of the disc spring are not machined.

The usual protective surface treatment is phosphate and oiled.
