Schnorr disc spring washer, Size 40 / 20.4 / 2.5mm

Disc springs can be used singly or stacked: stacking disc springs in series adds deflection and stacking them in parallel adds force. Size (mm), Internal Diameter Di (mm) and Thickness T (mm) are the option names, and the item names print the same three figures together dimensions, for example 6 x 3.2 x 0.3mm. Schnorr makes safety washers and disc springs for the automotive or aerospace industry and machine construction.

Key specifications

Choosing the right option

Choose by internal diameter Di first: it has to suit the bolt or shaft the washer sits on. Then match size (mm) and thickness T to the space you have and the spring force you need. Stacking disc springs in series adds deflection and stacking them in parallel adds force.
