Product description


With GN 7072.1 extension-tapped holes of the stainless steel two-piece shaft collars, GN 7062.10 sensor holders 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 set 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.
