Schnorr disc spring washer, Size 40 / 16.3 / 1.5mm

Schnorr makes safety washers and disc springs for the automotive or aerospace industry and machine construction.

Key specifications

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.
