Information

With extension-tapped holes of the split stainless steel shaft collars GN 7072.1, sensor holders GN 7062.10 or other elements such as the gear lever or cam can be attached to shafts and axles.

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 set 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.
