Product description


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

These shaft collars can easily be assembled with a high clamping force via the clamping screw without causing damage to the surface of the shaft or axle. As compared to semi-split shaft collars, split shaft collars can also be assembled radially.

For sizes d1 = 30 to 36 mm, d3 is a tapped through hole; for sizes d1 = 42 mm and larger, d3 is a tapped blind hole.
