Abstract: A chucking apparatus for chucking an object contains a basic body which has a receiving space in which the object can be disposed. A chucking device is provided with a chucking nut which is screwable onto the basic body and by the chucking nut being screwed onto the basic body the object disposed in the receiving space can be chucked non-rotatably. The chucking nut has a plurality of roller bodies having a defined roller engagement structure. The roller bodies are held in an axially rotatable manner on a chucking body of the chucking nut and are arranged distributed in the circumferential direction on the chucking nut. The rollers by their roller engagement structure are in engagement with the basic body engagement structure of the basic body.

Abstract: A clamping apparatus includes a spindle body and a nut element to be screwed together for decreasing a spacing between first and second clamping elements to clamp an object disposed therebetween. The nut element has roller bodies with a defined roller engagement structure axially rotatably secured on a receiving body of the nut element and distributed in circumferential direction. A plurality of engagement regions distributed and/or spaced apart on the spindle body each have one spindle body engagement structure. The roller engagement structures of the roller bodies engage or can engage the spindle body engagement structures of the spindle body. The nut element can be screwed to the spindle body by the mutually engaged engagement structures of the spindle body and of the roller bodies, in particular with rolling of the roller bodies on the spindle body. An apparatus and a vise having the clamping apparatus are also provided.
