Locking Washers

Disc Washers

Disc and conical spring washers, commonly known as Belleville washers, provide high axial force and dynamic tensioning within a compact spatial footprint. Their truncated cone geometry deflects under load to compensate for thermal cycling and gasket creep, maintaining critical bolt preload. They can be stacked in series or parallel configurations to customize load capacity and are vital in heavy-duty bolting, automotive transmissions, and precision pressure regulators.
