25030.0021 - Clamping Nuts
self-locking

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

This article 25030.0021 - Clamping Nuts self-locking / (d1: M20 x 1,5 mm, d2: 50 mm) is one variant of the article group Clamping Nuts self-locking (EH 25030.)

Notes

Further dimensions on request.

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.
