Clamping Nuts self-locking
EH 25030.
Clamping nuts are used for rotating parts, especially for reversible shafts, for example for fixing the grinding wheel. The compact construction ensures a safe function and allows quick installation using a face wrench.
Compared with other backup methods, the clamping nut has the following advantages:
- Self-locking (even with changing direction of rotation of the shaft)
- Easy installation / dismantling
- Also for repetitive clamping operations

Assembly
The clamping nut consists of an outer and inner ring, which form a unit.
The outer ring has a conical bore, the slotted inner ring has a conical outer surface and a female thread.
When tightening the clamping nut using a face pin wrench, the two conical surfaces move against each other. As a result, the slotted inner ring narrows like a collet. The nut clamps itself on the flanks of the thread so much, that they do not detach even with opposite axis rotation.
