DescriptionMaterial:Profile steel 1.7131.Version:Saw cut and deburred. Centre is centre-punched. Start and end of spiral is marked.Note:Spiral cams are used where something must be self-locking clamped or secured. The cam is operated mechanically, pneumatically or hydraulically using a shaft through the centre or a lever fastened to the side. By pressure failure the self-locking effect is still operative leading to much higher operating safety by pneumatic and hydraulic clamping.
