RÖHM presents type 525-00 LVE chucks. These chucks are suited for machining flanges and bar stock as well as for chucking pipes. The chuck body includes an actuating cylinder. It does not have a draw tube, which makes the spindle bore free and smooth throughout its full length. The immobilized floating ring 1 and the double nonreturn valve are used for supplying compressed air to one of the piston spaces.
The proven wedge system 4 is used by the chucking piston for transmission of the force acting on the pressure piston 3 to the base jaws 5. During the chucking and unchucking process, the floating ring 1 is sealed by special seals 6 against the body 7. Upon completion of the chucking operation, the nonreturn valve maintains the chucking pressure without any pressure present within the supply lines. The seals move up by their elasticity and are not damaged through the rotating chuck body.
The chucks are of self-contained type. They have a high gripping force, including at 6 bar.
