The affixed damping washer of the split shaft collars GN 7072.3 absorbs mild shocks and has a sound-damping effect when the shaft collars come into contact with other components.

They can be assembled safely and easily with a high clamping force by reducing the slot height, without damaging the surface of shafts and axles. As compared to semi-split shaft collars, split shaft collars can even be assembled radially.

The thread d₃ for sizes d₁ = 30 to 36 is designed as a through hole; for sizes d₁ = 42 and larger, it is designed as blind hole.
