SAV 241.41
Because the permanent electro magnetic workholding system is active when the device is de-energised, these chucks are preferably used where long holding times are required and no holding force is required only for short periods or occasionally. They are also used as safety magnets in transport systems and lifting gear, as the load is reliably held during a power failure. To achieve the rated holding force, the steel surfaces of the contact side must be fully covered by the workpiece.
