Information

Threaded shaft collars GN 706.3 correspond in outer dimensions to the semi-split shaft collars GN 706.2.

The bore has, however, an internal thread so that the clamping ring can be screwed in like a nut, for instance, to a spindle thread in order to limit the adjustment range or the screw-in depth.

The clamping is then done by reducing the slot height without damaging the thread.

The thread d₃ for sizes d₁ = 20 to 32 is designed as a through hole, from size d₁ = 42 and larger, it is designed as blind hole.
